Handling images in APEX 4.0

I am using APEX 4.0 and trying to rebuild an old Forms 6i application in this APEX 4.0 version. In Forms 6i there was the possibility to define an image with its size (I use 512 * 384 pixels). And I could also read an image from the file-system and resize it in a way that the complete image was vissible in the Application.
In Forms 6i I used the following code :
read_image_file ( fto
, 'JFIF'
, 'FOTO.EXAMPLE'
image_zoom ( 'FOTO.EXAMPLE'
, ADJUST_TO_FIT
Can anyone help me to implement this functionality in APEX 4.0 ?
Thanks,
Jos Straathof

Hi Jos,
I think there are 2 ways of going about this.
Method 1
Read the image into Oracle, resize it, and serve it up.
I'm not up-to-date with the latest version of Oracle, but I don't think it has a function to resize images built in, so you'd need an external library that you can call; or install a java library to do it. You'd read the image in as a BFILE, or use java to read it in. Not sure how you'd serve it up from APEX, but I know its possible.
Method 2
Set the HEIGHT and WIDTH attributes on the image when you generate the HTML and let the browser resize it. This is by far the easiest method.
eg <IMG SRC='myimage.jpg' HEIGHT=240 WIDTH=320>
Comming from a forms 6i background, I have the same problem - I keep comparing Apex to forms. But they are radically different beasts, and I'm trying to unlearn everything I know.

How to grey out images in APEX

Hi,
Can someone let me know how can I disable/greyout images in APEX?
I have a list of images in a horizontal way, say Image 1, Image 2, Image 3, Image 4.
So when Image 1 is accessed, Image 2,3 and 4 should be greyed out. When Image 2 is accessed, Image 3 and 4 (not Image 1) should be greyed out and so on.
Please let me know how can this be done?

What you mean by "Image is accessed"?
Do you mean when mouse click image or hover mouse over image?

How do you display a image in apex

I have a trouble for a long time..
I can't load a image in apex..
I do a lot of things but it never give result correctly
some could help me..
Thank u....

Hi,
OK - the link I gave will explain how to upload into a table and then display images from there.
To do this through Shared Components:
1 - Go to Shared Components
2 - Select Images
3 - Click Create
4 - In the Application option, leave it as "No Application Associated" if you want any application to use the image, or select an application if the image is for that application only
5 - Click the Browse button, locate your image file on your machine and click Open
6 - Any any Notes you want (this is not required)
7 - Click Upload
On your page, decide where you want the image to appear. This can be in a region's Source, Region Header or Region Footer OR if you want you can do this on the page template you are using. Then enter in:
For an image NOT associated with an application:
<img src="#WORKSPACE_IMAGES#filename.gif">For an image associated with an application:
<img src="#APP_IMAGES#filename.gif">Andy

Regarding Timo Hahn blog: Handling images/files in ADF (Part 2)

Hello All, specially Timo Hahn :).
I am using Jdeveloper 11.1.2.3.0, ADF BC, ADF Faces, Windows 7.
And I am trying to Handle image/files (download,upload,view for images) from database as explained in Timo's post
http://tompeez.wordpress.com/2011/11/26/jdev11-1-2-1-0-handling-imagesfiles-in-adf-part-2/
I installed the commons-io-2.4-bin.zip file, but I don't know how to add it to my view controller project.
Any help is appreciated.

Thank you,
But I have one question. I am not expert in Java, but from my understanding the Library is a collection of jar files. So the file I installed is considered a library because it has jar 5 files.
suppose I want to add the entire library to my project, can we do this:
By the way I tried to do this by:
1- double click the view controller project, select library and class path, click the Add Library button.
2- From the Add Library Window, i clicked the new button.
3- from the create library window I enter a name and i class path I select the folder contacting these jars and then press OK
But this did not work for me, and get these errors
Error(30,29): package org.apache.commons.io does not exist
Error(125,13): cannot find variable IOUtils
Error(157,13): cannot find variable IOUtilsBut when I add a single jar to my project it works fine.
So, is it possible to add the entire library to my project?

Can LabVIEW process images in RAW format? Can LabVIEW handle images in the multimegapixel formats produced by some of the current DSLR cameras (e.g. 5000x3500 pixels)?

Can LabVIEW process images in RAW format? Can LabVIEW handle images in the multimegapixel formats produced by some of the current DSLR cameras (e.g. 5000x3500 pixels)?
Can LabVIEW be programmed to remotely acquire images from a commercial DSLR camera with DirectShow capability? e.g. Canon Rebel T2i.

1) So RAW files have a multitude of possible file extensions / formats, and it depends on which of these extensions you use. If the image can fit in memory, it can be brought into LabVIEW. An image of that size should be able to come into LabVIEW. Are you considering using NI-Vision to do this? You would look into the VI called "IMAQ ReadFile." There are a certain set of standard formats that can be read.
2) If a camera is DirectShow capable, and there are USB drivers available to access that camera through a Windows machine, then you should be able to bring that camera up in NI's software such as LabVIEW.

Saving & populating images in apex

hi
I want to save & retrieve employee photoes in database using apex. can anyone help me.
vijay

Hi Vijay,
Inside your workspace do you have sample application-> Run it->Go to Tab-> product-> Click Create Product-> Form shows input field with browse button-> Edit page to see the code to implement saving & populating images in apex.
This is table based storage inside apex.
If you want to store inside apex for your designing then go to shared component -> image-> create new image uploading-> Access from your page will be like the below.
<img src=#APP_IMAGES#temp.jpg>
This link also help.

How does RH7 handle Images?

Could someone please take a moment and tell me how RH7
handles images? Does RH7 keep images in their location and just
reference them...i.e. If I create an image folder on the server,
will it just reference them from there or does it create a copy of
the image and store them elsewhere?
I have a very large help site and with multiple section, and
we merge them all together. Each section has many images - with
some images used across sections. I am trying to figure out the
most efficient way to handle them. Based on the help here, I have
decided that snippets will be the best option. However, in order
for me to use them effectively I need to understand the underlying
process. Also, does anyone have a better suggestion on how this
could be done?
Thanks in advance for the assist.

Images must be in the project. When you import an image, it
is copied to your project. It cannot be outside.
Even with merged help, the images have to be within the
specific project and that can mean duplication.

Capture Web Cam image in APEX and Upload into the Database

Overview
By using a flash object, you should be able to interface with a usb web cam connected to the client machine. Their are a couple of open source ones that I know about, but the one I chose to go with is by Taboca Labs and is called CamCanvas. This is released under the MIT license, and it is at version 0.2, so not very mature - but in saying that it seems to do the trick. The next part is to upload a snapshot into the database - in this particular implementation, it is achieved by taking a snapshot, and putting that data into the canvas object. This is a new HTML5 element, so I am not certain what the IE support would be like. Once you have the image into the canvas, you can then use the provided function convertToDataURL() to convert the image into a Base64 encoded string, which you can then use to convert into to a BLOB. There is however one problem with the Base64 string - APEX has a limitation of 32k for and item value, so can't be submitted by normal means, and a workaround (AJAX) has to be implemented.
Part 1. Capturing the Image from the Flash Object into the Canvas element
Set up the Page
Required Files
Download the tarball of the webcam library from: https://github.com/taboca/CamCanvas-API-/tarball/master
Upload the necessary components to your application. (The flash swf file can be got from one of the samples in the Samples folder. In the root of the tarball, there is actually a swf file, but this seems to be a different file than of what is in the samples - so I just stick with the one from the samples)
Page Body
Create a HTML region, and add the following:
    <div class="container">
     <object id="iembedflash" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0" width="320" height="240">
          <param name="movie" value="#APP_IMAGES#camcanvas.swf" />
          <param name="quality" value="high" />
          <param name="allowScriptAccess" value="always" />
          <embed allowScriptAccess="always" id="embedflash" src="#APP_IMAGES#camcanvas.swf" quality="high" width="320" height="240"
type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" mayscript="true" />
    </object>
    </div>
<p><a href="javascript:captureToCanvas()">Capture</a></p>
<canvas style="border:1px solid yellow" id="canvas" width="320" height="240"></canvas>That will create the webcam container, and an empty canvas element for the captured image to go into.
Also, have a hidden unprotected page item to store the Base64 code into - I called mine P2_IMAGE_BASE64
HTML Header and Body Attribute
Add the Page HTML Body Attribute as:
onload="init(320,240)"
JavaScript
Add the following in the Function and Global Variable Declarations for the page (mostly taken out of the samples provided)
//Camera relations functions
var gCtx = null;
var gCanvas = null;
var imageData = null;
var ii=0;
var jj=0;
var c=0;
function init(ww,hh){
     gCanvas = document.getElementById("canvas");
     var w = ww;
     var h = hh;
     gCanvas.style.width = w + "px";
     gCanvas.style.height = h + "px";
     gCanvas.width = w;
     gCanvas.height = h;
     gCtx = gCanvas.getContext("2d");
     gCtx.clearRect(0, 0, w, h);
     imageData = gCtx.getImageData( 0,0,320,240);
function passLine(stringPixels) {
     //a = (intVal >> 24) & 0xff;
     var coll = stringPixels.split("-");
     for(var i=0;i<320;i++) {
          var intVal = parseInt(coll);
          r = (intVal >> 16) & 0xff;
          g = (intVal >> 8) & 0xff;
          b = (intVal ) & 0xff;
          imageData.data[c+0]=r;
          imageData.data[c+1]=g;
          imageData.data[c+2]=b;
          imageData.data[c+3]=255;
          c+=4;
     if(c>=320*240*4) {
          c=0;
          gCtx.putImageData(imageData, 0,0);
function captureToCanvas() {
     flash = document.getElementById("embedflash");
     flash.ccCapture();
     var canvEle = document.getElementById('canvas');
     $s('P2_IMAGE_BASE64', canvEle.toDataURL());//Assumes hidden item name is P2_IMAGE_BASE64
     clob_Submit();//this is a part of part (AJAX submit value to a collection) two
}In the footer region of the page (which is just a loading image to show whilst the data is being submitted to the collection [hidden by default]) :<img src="#IMAGE_PREFIX#processing3.gif" id="AjaxLoading"
style="display:none;position:absolute;left:45%;top:45%;padding:10px;border:2px solid black;background:#FFF;" />If you give it a quick test, you should be able to see the webcam feed and capture it into the canvas element by clicking the capture link, in between the two elements - it might through a JS error since the clob_Submit() function does not exist yet.
*Part 2. Upload the image into the Database*
As mentioned in the overview, the main limitation is that APEX can't submit values larger than 32k, which I hope the APEX development team will be fixing this limitation in a future release, the workaround isn't really good from a maintainability perspective.
In the sample applications, there is one that demonstrates saving values to the database that are over 32k, which uses an AJAX technique: see http://www.oracle.com/technetwork/developer-tools/apex/application-express/packaged-apps-090453.html#LARGE.
*Required Files*
From the sample application, there is a script you need to upload, and reference in your page. So you can either install the sample application I linked to, or grab the script from the demonstration I have provided - its called apex_save_large.js.
*Create a New Page*
Create a page to Post the large value to (I created mine as 1000), and create the following process, with the condition that Request = SAVE. (All this is in the sample application for saving large values).declare
     l_code clob := empty_clob;
begin
     dbms_lob.createtemporary( l_code, false, dbms_lob.SESSION );
     for i in 1..wwv_flow.g_f01.count loop
          dbms_lob.writeappend(l_code,length(wwv_flow.g_f01(i)),wwv_flow.g_f01(i));
     end loop;
     apex_collection.create_or_truncate_collection(p_collection_name => wc_pkg_globals.g_base64_collection);
     apex_collection.add_member(p_collection_name => wc_pkg_globals.g_base64_collection,p_clob001 => l_code);
     htmldb_application.g_unrecoverable_error := TRUE;
end;I also created a package for storing the collection name, which is referred to in the process, for the collection name:create or replace
package
wc_pkg_globals
as
g_base64_collection constant varchar2(40) := 'BASE64_IMAGE';
end wc_pkg_globals;That is all that needs to be done for page 1000. You don't use this for anything else, *so go back to edit the camera page*.
*Modify the Function and Global Variable Declarations* (to be able to submit large values.)
The below again assumes the item that you want to submit has an item name of 'P2_IMAGE_BASE64', the condition of the process on the POST page is request = SAVE, and the post page is page 1000. This has been taken srtaight from the sample application for saving large values.//32K Limit workaround functions
function clob_Submit(){
          $x_Show('AjaxLoading')
          $a_PostClob('P2_IMAGE_BASE64','SAVE','1000',clob_SubmitReturn);
function clob_SubmitReturn(){
          if(p.readyState == 4){
                         $x_Hide('AjaxLoading');
                         $x('P2_IMAGE_BASE64').value = '';
          }else{return false;}
function doSubmit(r){
$x('P2_IMAGE_BASE64').value = ''
     flowSelectAll();
     document.wwv_flow.p_request.value = r;
     document.wwv_flow.submit();
}Also, reference the script that the above code makes use of, in the page header<script type="text/javascript" src="#WORKSPACE_IMAGES#apex_save_large.js"></script>Assuming the script is located in workspace images, and not associated to a specific app. Other wise reference #APP_IMAGES#
*Set up the table to store the images*CREATE TABLE "WC_SNAPSHOT"
"WC_SNAPSHOT_ID" NUMBER NOT NULL ENABLE,
"BINARY" BLOB,
CONSTRAINT "WC_SNAPSHOT_PK" PRIMARY KEY ("WC_SNAPSHOT_ID")
create sequence seq_wc_snapshot start with 1 increment by 1;
CREATE OR REPLACE TRIGGER "BI_WC_SNAPSHOT" BEFORE
INSERT ON WC_SNAPSHOT FOR EACH ROW BEGIN
SELECT seq_wc_snapshot.nextval INTO :NEW.wc_snapshot_id FROM dual;
END;
Then finally, create a page process to save the image:declare
v_image_input CLOB;
v_image_output BLOB;
v_buffer NUMBER := 64;
v_start_index NUMBER := 1;
v_raw_temp raw(64);
begin
--discard the bit of the string we dont need
select substr(clob001, instr(clob001, ',')+1, length(clob001)) into v_image_input
from apex_collections
where collection_name = wc_pkg_globals.g_base64_collection;
dbms_lob.createtemporary(v_image_output, true);
for i in 1..ceil(dbms_lob.getlength(v_image_input)/v_buffer) loop
v_raw_temp := utl_encode.base64_decode(utl_raw.cast_to_raw(dbms_lob.substr(v_image_input, v_buffer, v_start_index)));
dbms_lob.writeappend(v_image_output, utl_raw.length(v_raw_temp),v_raw_temp);
v_start_index := v_start_index + v_buffer;
end loop;
insert into WC_SNAPSHOT (binary) values (v_image_output); commit;
end;Create a save button - add some sort of validation to make sure the hidden item has a value (i.e. image has been captured). Make the above conditional for request = button name so it only runs when you click Save (you probably want to disable this button until the data has been completely submitted to the collection - I haven't done this in the demonstration).
Voila, you should have now be able to capture the image from a webcam. Take a look at the samples from the CamCanvas API for extra effects if you wanted to do something special.
And of course, all the above assumed you want a resolution of 320 x 240 for the image.
Disclaimer: At time of writing, this worked with a logitech something or rather webcam, and is completely untested on IE.
Check out a demo: http://apex.oracle.com/pls/apex/f?p=trents_demos:webcam_i (my image is a bit blocky, but i think its just my webcam. I've seen others that are much more crisp using this) Also, just be sure to wait for the progress bar to dissappear before clicking Save.
Feedback welcomed.

Hmm, maybe for some reason you aren't getting the base64 version of the saved image? Is the collection getting the full base64 string? Seems like its not getting any if its no data found.
The javascript console is your friend.
Also, in the example i used an extra page, from what one of the examples on apex packages apps had. But since then, I found this post by Carl: http://carlback.blogspot.com/2008/04/new-stuff-4-over-head-with-clob.html - I would use this technique for submitting the clob, over what I have done - as its less hacky. Just sayin.

How to handle images stored /outside/ Aperture

I am coming from a PC environment where my images were stored all over my hard drive in various folders and subfolders. I am part-way through organizing all of this in Aperture but I OFTEN find myself exporting images to folders on my desktop in order to upload them to FTP or edit them in Photoshop conveniently and as I move to working in something like an Adobe Suite that allows me to edit and link images I do see myself keeping images outside of Aperture.
Can anyone help me out with how to manage this a little more practically (say by only keeping images on the desktop but not in the Documents Folder) and/or should I be trying to discipline myself down to keeping everything in Aperture? I find it relatively confusing to do it this way but am very interested in getting some advice on this.
Thanks,
Jon

Jon,
I used to have everything sorted with the top folder being 'Project 1', 'Project 2', 'Project 3', etc. with either all files in that folder, or sub-folders for each file type. This was pretty good, but eventually got out of hand once I had a couple hundred projects with all types of files in each folder and needed to find a specific file (say an Illustrator file I needed to work on).
Now, I use the following structure for Adobe CS5 projects:
Top level folder = 'Design Files'
Second level folders = 'Photoshop Files', 'Illustrator Files', 'InDesign Files', 'Acrobat Files'
Third level folders (inside each of the second level folders as needed) = 'Project 1', 'Project 2', 'Project 3', etc.
This gives me all my PSD files inside one master 'Photoshop Files' folder divided by Project folders. If - for example - Project 1 has PSD files, AI files, IND files and PDF files, then there is a Project 1 folder under each of the second level folders for each program. This allows me easy access to either all files for a program by going to that folder, or I can run a dynamic search (smart folder) for a project and see all relevant folders for that project in the search results.
The main reason I have it this way now is that I usually remember the file type (as mentioned above for an Illustrator file). I typically remember that I did an illustration, but can't remember the file name of the illustration or the project it went in for sure. My current structure shortens my search time considerably.
Note - I can also use Bridge CS5 very easily for the Adobe CS5 files since it shows thumbnails of the actual file and I can visually search very fast that way.
At home - with Aperture - I only hold the original images (pictures) that I started to work with. I don't keep any PSD, TIFF, PDF, PNG, etc. in the library. This is simply because Bridge is much better at showing those files with transparency if it exists, and Aperture stays a straight-forward image (picture) database for me.
If I send an image to a plug-in or to Photoshop from inside Aperture, I do it for a specific purpose and then I complete the process and export it to one of the dedicated folders in Finder (typically to my Photoshop Files folder). If I really need to keep the layer work in a PSD file, then I will use the 'Save As' command from inside Photoshop to save out to a folder and then just trash the file Aperture sent to Photoshop. Although I have not had any real issues with Aperture holding PSD files in the past, I simply trust Adobe to handle their own files without relying on Apple's program to do it for me.
As far as miscellaneous files (screenshots, scans, web icons), I really don't do many of those. I have a few scans which are not part of any project and just keep those in a two level folder (Art / Scans). For web icons, I would probably suggest going with the program you used for a folder (Photoshop Files?). Not sure what program or file type you are using for those (GIF, PNG - I don't work with web design so not real familiar with current practices for icon design for the web).
For JPEG files, I use a second level 'JPEG files' folder for any JPEG's that are used in my design projects in a 'Project 1', 'Project 2', etc. folder (same as the other file types mentioned above). Although, I typically use PSD files as source files and then save out JPEG's on a case-by-case basis (similar to using Aperture as the source and exporting as needed).
Since most of my design files are for InDesign projects, I complete the project by embedding all links in the document after having printed to PDF (and proof-reading prior to embedding). This protects against lost links if I need to work with the master file again for some reason. I can always place a new image or file in the document as needed and since I have a PDF of the file to send to collegues, the extra file size in the InDesign file after embedding is not a big deal.
So, in summary; I use a top level folder (based on category; e.g., Design Files) and then organize by file type parent folders with dedicated project folders under those as needed. Works for the way I think.
I hope that was somewhat clear.
Message was edited by: CorkyO2 to change "top level file" to "top level folder" in summary.

Best practice for images in APEX

Hello All,
I use APEX 4.2.2 .. Oracle 11g SOE...
Speaking about the sample DB application. Suppose each product has more than one image. And that we have two Apps desktop & Mobile. Suppose Product A has 5 images.
===>>
Does it mean that for Product A, I have to store 12 images as following:
5 images for Desktop App where dimensions are e.g 640 x 480
5 images for Mobile App where dimensions are e.g 448 x 336
1 Thumbnail for desktop App 104 x 104 ( To show up on the report )
1 Thumbnail for mobile App 50 x 50 ( To show up on the report )
Here I noticed that the image are begin resized on the fly. As we upload images, we get thumbnails. Any comments ???
http://blueimp.github.io/jQuery-File-Upload/angularjs.html
Regards,
Fateh

Hello Roel,
Thanks for the response. I am aware of Oracle Multimedia. Maybe, I was not clear. As I got from you, you agree that I have to store 2 editions of each image one for desktop and the other for mobile.
do the proper scaling in the application itself.You mean I can use Height and Width Attributes of the img Tag to scale the images to be used in Report / List . But as I know this does not reduce the size of the image. If the list shows 20 record with 20 images, the mobile webpage will be slow.
So, do you agree that I have to generate a two thumbnails (one for desktop and another for mobile ) for each PRODUCT, or you were refereeing to something else ?
Regards,
Fateh

What do you suggest how to handle images?

Hello,
I would like to develop a book administration program in web dynpro but I have no clue how to handle the images. There are several points I would like to take care about. The frontend is wd4a and the backend is abap. There will also be an iPhone App that connects via WebServices that also need the data and the images.
What do you think is the best possibility to save the images?db via blob, file system, ...
Are there examples how to upload the images via web dynpro and transfer it to the backend?
Thanks a lot in advance,
Vanessa

Hello,
I'd echo Neil's thoughts - definitely store your images in tables as they are transactional data. Creating a DB table with variable length data isn't difficult - just specify the datatype as rawstring.
You can then easily read from the db and serve these images in image UI elements, I'm guessing the row repeater UI element is going to be very useful for you.
Does sound like a good fun project!
Cheers,
Chris

How to handle images

Hello,
I am developing a little application with functions for a library.
I would like to show a picture of the book in the book overview.
What is the best practice to handle the image. Uploading it with the WD4A-GUI to the backend?
Where would you save the images (frontend, backend,... ?)
Thank you,
Vanny

hi ,
save it as mime
right click ur application and then click on create mime object.
with Mime Objects u cn upload doc , jpeg, or giff files from our local system into the webdypnpro system .
You can even try creating the MIME objects in webdynrpo abap .
Right click on ur component->mime object->import
In the transaction sicf/bc/webdynpro , u cn check your component name there you can view the mime objects created by you .
also refer the SAP online help :

How to handle images (or let say mimes)

Dear MDM Gurus,
I want to start a discussion on how to handle MIMEs in MDM best.
Szenario is MDM as a SRM Catalog System - Some million products(records) and as many mimes.
- Import or linking?
- What are the pros and cons of these two ways?
- If I link images can MDM Server deliver them or do I need a seperate Webserver?
- If I import them how will the DB Size extend?
- If I "only" link the does it make a difference while lookup at import?
Maybe some of you have more questions and hopefully some of you have a kind of best-practice help for us.
Best regards

Hi Roman,
Its a nice discussion you have started. According to me
Advantage of linking
1. You can store the millions of images in the separate machine so the disk space on which SQL Server is installed can be used to store other data.
Disadvantage of linking
1. It may take some time to load the repository or in accessing the MDM clients because system has to actually search the location and fetch the mimes where they are stored.
Advantage of Storing
1. Loading and Opening of MDM Clients time can be reduced since all the images are stored in the repository itself
Disadvantage of Storing
1. If there are millions of images as you have said then majority of drive space will be used by these mimes and hence we can create less MDM records
Note: Sounds, Videos when stored in the repository cannot be played directly from the MDM Data manager they are first saved some where then only we can play them while this is not the case with linking

How to use custom images in Apex 4.1 with EPG

I just ported over an application from Apex 3.2/10g using Apache to a new server using Apex 4.1/11g using EPG and none of my custom images work. When using Apache, all I had to do was copy the file over to the /i/Custom images folder and I could reference it on any of my pages. I copied the entire /Custom folder to the new server and that doesn't seem to do the trick. I've seen some posts that talk about having to use FTP (why?) or something to get this to work. Can someone please explain what is going on here and what I need to do to get this working?

With EPG, the images aren't accessed from a directory. They are actually stored inside the database. The FTP process actually gets redirected so that the image gets stored inside Oracle rather than being written to a file. There are numerous articles and such detailing exactly how to do this.
One is here:

Referencing loaded images in APEX

Hi all:
Up until this point, I have used the same method of getting images to be recognized by an Apex
installation. That specifically has been through loading images into a physical directory on the
machine where APEX was installed. This was made available to me by the DBA that installed APEX.
This is Application Express 2.2.0.00.32 running on AIX Unix.
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
This arrangement worked. I was able to reference any image loaded to that directory using
"/i/[image].gif". "/i/" was set as my pseudo directory by default on Apex.
Over time, I developed an application that is now ready to deploy in like environments and I have
never had a problem with viewing graphics.
For the purposes of demoing to a specific customer, I was asked to deploy this to a different environment
temporarily, I was given the option of loading my application to a Windows XP environment running
Oracle XE and Application Express 2.1.0.00.39.
Since there was no physical directory that I could locate for images, it seemed to me that my only
option was to load my images using the wizard for loading image file components (which I understand
means using XDB)...
I was not been able to get this to work. I went back to my AIX Unix/Oracle 10g installation and attempted
to do the same (load images as a file component and reference them). To my surprise it didn't work there
either.
These are the steps I took in attempting this:
1.) Within my application definition, go to "Shared components"
2.) Under the Files section, I click on "images"
3.) Click on the button labeled "Create"
4.) The page "Create Image" appears. I click on the "Browse" button and I pick the image from my local file system.
5.) I leave the drop-down list as is (reading "No Application Associated")
6.) I click on the "Upload" button.
I then go back to my application under "Edit Attributes" and reference the file as /i/[file].gif
I find that the images do not show up. On IE, all I get is the standard red "X" indicating that
an image file failed to load.
I can't help thinking that I'm missing an obvious step. Let me know if there's any other info I should
provide.
Thanks

HI,
To reference images loaded through shared components use:
#WORKSPACE_IMAGES#filename.gif (when you set it to No Application Associated)
or
#APP_IMAGES#filename.gif (when you associate it with a specific application)
