Display Images from HTMLDB_APPLICATION_FILES Table?

How do I display images from the HTMLDB_APPLICATION_FILES Table?
Are the contents full available potentially for display? Or only after I have written them to another display?
Please advise what I need to do or what corrections below is required:
The calling procedure is a item in a SELECT statement as part of a report query:

<(img src="#OWNER#.download_HAF_file?p_file= ' || nvl(ID,0) || ' height="50" width="50" )>, HAFimg
The Procedure is a adaptation of the Chapter 8 Exercise of the 2 day developer guide:
CREATE OR REPLACE PROCEDURE "DOWNLOAD_HAF_FILE" (p_file IN NUMBER) AS
 v_mime VARCHAR2(48);
 v_length NUMBER;
 v_file_name VARCHAR2(2000);
 Lob_loc BLOB;
BEGIN
 SELECT MIME_TYPE, BLOB_CONTENT, NAME, DBMS_LOB.GETLENGTH(BLOB_CONTENT)
 INTO v_mime, lob_loc, v_file_name, v_length
 FROM HTMLDB_APPLICATION_FILES
 WHERE ID = p_file;
 -- set up HTTP header
 -- use an NVL around the mime type and
 -- if it is a null set it to application/octect
 -- application/octect may launch a download window from windows
 owa_util.mime_header( NVL(v_mime,'application/octet'), FALSE );
 -- set the size so the browser knows how much to download
 htp.p('Content-length: ' || v_length);
 -- the filename will be used by the browser if the users does a save as
 htp.p('Content-Disposition: attachment; filename="'||SUBSTR(v_file_name,INSTR(v_file_name,'/')+1)|| '"');
 -- close the headers
 owa_util.http_header_close;
 -- download the BLOB
 wpg_docload.download_file( Lob_loc );
END Download_HAF_File;

I believe you put HTML "pre" tags around your quote (with square brackets, I can't type them here because they'll be escaped).
If the example below looks formatted then using "pre" works, if not...then ignore me ;)
begin
select
 count(*)
into
 v_count
from big_table;
end;

Display images from a SQL database

I want to display images from a SQL database. The images are in a table under a specific column and are stored as a link to the image. How would I display the images from the column in LabVIEW?
I'm using LabVIEW 2013 version 13 and SQL Server 2012

I have not lost my mind, it's backed up on a disk somewhere

Hi PauldePaor,
I hope you are well.
Once you have pulled the data from the database into LabVIEW in a string form (or path), you can simply use the Read BMP File (Or jpg, png depending on the file type) VI.

Pages 5.0 removing images from tables.

After upgrading to Pages 5.0 I now receive a message when opening any file with a table that has images in the cells. Basically Pages is removing all images from table cells. Anyone having this problem and is there an easy fix?

DrBrian, this is what I did to resolve this issue. I found out that we may still have Pages 09 installed on our systems! Go into Finder - Applications. If you have a folder titled iWork 09 click it and you may find Pages 09 there. Double click to open Pages version 09 where you will be able to open all of your files just as they should be.
I will not be using the new Pages upgrade. I have too much time invested in creating documents and templates for my business and I am not willing to re-learn a new package which has much less functionality. Hope this helps you.

Hello,
It is very difficult for us to "guess" what images you can read and what others you cannot.
Maybe you could provide more information on images that are not displayed ?
What is their native format ?

My iphone 4s suddenly displays images from Yahoo, Google, and Flickr at low resolution. The camera on my phone works fine, but any web related photo content is now pixelated and low res, what's the deal?

My iphone 4s suddenly displays images from Yahoo, Google, and Flickr at a low resolution. I have IOS 7.0.4. My phone camera works fine, but any web based photo content from Safari, Yahoo images, Google images, and Flickr all come in pixelated and low res. What's the deal?

It happened to me but later I figured out that cellular signal was not that great and so the Internet was very slow. It took me about 2 minutes to get the full resolution picuture on either of the app you've described. Try to get faster internet either by wifi or good signal and then check.

Displaying image from database table.

Hi All,
   I am very new to Web Dynpro ABAP.
I am developing an application to display an image in "Image" UI Element.
For this I have one table consisting of fields image id, image data and image name. here image id is primary key field.
Now i want to display an image from that table in "Image" UI Element. For this i am using "Filedown load" UI element.
But by using filedownload ui element i can diaplay image in another new page.
But my requirement is to display image in the same web page without creating a new one.
(I want to display the image in "Image" UI element without storing that image in MIME objects.)
Can anyone help me.
Thanks in Advance!
Regards,
Sreelakshmi.

What you describe is completely possible. Since you have the image data (XSTRING) in the context you have everything you need. You don't need to store the content into the MIME Repository, but you do need to get it somewhere where it has an externally accessible URL. Remember you need to supply image UI element with a URL. This URL is processed on the client side by the web browser. Therefore just giving it a path to the context won't work as that isn't externally accessible.
I would suggest instead that you place the image content into the ICM cache temporarily. This lets you basically generate a temporary URL for the image that can be used by the Image UI element.
Here is some example code that pushes images into the ICM Cache:
****Create the cached response object that we will insert our content into
DATA: cached_response TYPE REF TO if_http_response.
CREATE OBJECT cached_response
    TYPE
      cl_http_response
    EXPORTING
      add_c_msg        = 1.
   try. " ignore, if compression can not be switched on
      call method cached_response->set_compression
        exporting
          options = cached_response->co_compress_based_on_mime_type
        exceptions
          others = 1.
    catch cx_root.
endtry.
****set the data and the headers
DATA: l_app_type TYPE string.
DATA: l_xstring TYPE xstring.
      cached_response->set_data( me->gx_content ).
      l_app_type = me->gx_mimetype
cached_response->set_header_field( name = if_http_header_fields=>content_type
                                     value = l_app_type ).
****Set the Response Status
cached_response->set_status( code = 200 reason = 'OK' ).
****Set the Cache Timeout - 60 seconds - we only need this in the cache
****long enough to build the page and allow the Image on the Client to request it.
cached_response->server_cache_expire_rel( expires_rel = I_CACHE_TIMEOUT ).
****Create a unique URL for the object
DATA: guid TYPE guid_32.
CALL FUNCTION 'GUID_CREATE'
    IMPORTING
      ev_guid_32 = guid.
CONCATENATE i_path '/' guid '.' i_format INTO r_url.
****Cache the URL
cl_http_server=>server_cache_upload( url      = r_url
                                       response = cached_response ).

Displaying BLOB images from table in a report

I am trying to upload images to a table, display them in a report afterwards. I have succeeded in the first part, but not in the second. 
 
I can display images in a report if they are in located in wwv_flow_file_objects$ where they are automatically put after 'File browse... + Submit'. 
But, if I move (insert into table + delete from ..object$) I cant display it in a report correctly. I saw the HOWTO document (the code was from there), but for some reason, it doesn't work. 
 
What am I doing wrong? How should I correct the column link or the procedure? 
 
REPORT SQL: 
 
id, 
name, 
filename, 
img src="display?p_photo_id=' || nvl(id,0) || '" height="50" width="50"' 
--wwv_flow_file_objects$ display 
--img src="p?n=' || nvl(id,0) || '" height="50" width="50" ' img, 
BLOB_CONTENT, 
MIME_TYPE 
from images; 
PROCEDURE 'display': 
create or replace procedure display (p_photo_id in number) 
as 
l_mime varchar2(255); 
l_length number; 
l_file_name varchar2(2000); 
lob_loc BLOB; 
begin 
select mime_type, blob_content, name, dbms_lob.getlength(blob_content) 
into l_mime, lob_loc, l_file_name, l_length 
from images where id = p_photo_id; 
owa_util.mime_header(nvl(l_mime,'application/octet'), FALSE ); 
htp.p('Content-length: ' || l_length); 
htp.p('Content-Disposition: filename="' || l_file_name || '"'); 
owa_util.http_header_close; 
wpg_docload.download_file( Lob_loc ); 
end; 
 
Many thanks! 

Alayan - If you're using XE, that shoud be the first thing you tell us. There is a separate forum for that product.
But as long as you're here, a couple points: you reference the "display" procedure in the img tag without qualifying it with an owner. How is the Embeded PL/SQL Gateway supposed to know what "display" is (unless you created a public synonym)? Next, in XE you need to explicitly enable access to procedures that are invoked this way. See the XE forum for discussion about that technique and read the doc here: http://download-uk.oracle.com/docs/cd/B25329_01/doc/appdev.102/b25309/adm_wrkspc.htm#BEJCGJFJ.

Fetching an image from table to be displayed in HTML

I'm making something similar to the [online store Packaged Applications from Oracle.|http://www.oracle.com/technology/products/database/application_express/packaged_apps/packaged_apps.html]
I have small problem.
<td rowspan="5" valign="top"><img src="f?p=&APP_ID.:30:0:#IMG#" width="50" height="50"></td>
This is how the image is fetch from table EBA_OLS_IMAGES in the online store app. The parameter #IMG# is the id of the image, not the blob file.
So can some one explain to me how this link works.. What the .:30:0: means.

Displaying image from database in report

I need to include a picture (company logo) in numerous reports. This logo will be stored in an MS SQL Image field in a table (this bit I have already sorted out).
What I'm wondering is, what is the best way to retrieve this image from the database? Do I just include it in the view the report runs off? I'm hesitant to do this, as the view may return back hundreds of records, which means (I think) it will be sending the image along with it hundreds in time.
In short:
1) What is the best way to pass an image to a report.
2) If I include the Image field in a view which returns back hundreds of line, will the image be returned also hundreds of time, causing network congestion/performance issues?
3) If so (2), is there a way of sending the image only once, no matter how many rows are in the returned view?
Thanks.

Hi Shanon,
We can display the image by making it a local copy on your machine.
If it is possible to get the image saved on local copy.
If we place the image in detail section then it would return one record.
As the image is from Database, so it would hit the database very time when you refresh the report and place it in Report Header or report fotter.
So, place your logo as an OLE object in report and would reduce processing time.

Naveen.

How to display images from BLOB column via APEX 4.0

Hello,
I did the following in order to display images of two Oracle records on the APEX page. I am using APEX Version : 4.0.1.00.03 , Oracle DB Version : 10.2.0.4.0.
1. Created An oracle table TEST_FORM
with 3 columns
( ID number, MIME_TYPE varchar2(255) , Image BLOB )
2. Inserted two records
10001, image/gif, ( actual image1)
10002, image/gif, ( actual image2)
3. created an Oracle procedure
CREATE OR REPLACE PROCEDURE show_my_form ( p_image_id IN test_form.id%type) AS
l_mime test_form.mime_type%type;
l_length NUMBER;
l_file_name VARCHAR2 (2000);
lob_loc test_form.IMAGE%type;
BEGIN
SELECT mime_type, IMAGE
, DBMS_LOB.getlength (IMAGE)
INTO l_mime, lob_loc, l_length
FROM test_form
WHERE id = p_image_id;
owa_util.mime_header(l_mime, false);
htp.p ('Content-length: ' || l_length);
owa_util.http_header_close;
wpg_docload.download_file (lob_loc);
END show_my_form ;
4. In Apex 4.0
step1. Created an interactive report on a new APEX page
step2. Specified the following in the Region Source
select id, mime_type, '<img src="#OWNER#.show_my_form ?p_image_id=#ID#" />' photo
from TEST_FORM
The column result shows as <img src="CCS.show_my_form?p_image_id=#ID#" />
I am unable to display the column image as a link to a proper image photo.
Could you please advise me if I missed anything ?
Thanks a lot.
Regards
Susanna

Maybe the space you have before the ? is causing issues. there shouldn't be any space.
Your procedure looks to be much the same of one that I have.
Have you granted execute on your procedure?
Also, what version DB are you running? This could be another issue: http://daust.blogspot.com/2006/04/xe-calling-stored-procedures.html
But anyway, you don't need to create your own procedure these days. You could do the following:
in your query, have a column: dbms_lob.getlength(blob) photo ; save, then in column attributes for that column, apply a format mask. There is usually a link below the text box for the format mask - BLOB Download Format Mask, which will help you build the format mask. But it is documented here: http://download.oracle.com/docs/cd/E17556_01/doc/user.40/e15517/advnc.htm#BCGGJHEF

Displaying image from Database with php

Hello everybody,
I'm working on a website that displays videos courses and tutorials as my final project
and I'm working with "Flash builder 4" the database with mySQL and the application server with php
Basically, the goal is to display a datagrid that shows the manager of the website in column all the information stored on the "Course" table
the structure of the table is :
Course (id,img,src,title,description)
-id : primary key
-img : path to a photo of course {for example picture of JAVA}
-src : path to the playlist file {xml file}
-title : String
-description : String too
I already succeeded to display all these contents on a DataGrid, but not with the image, I couldn't display an imageon its column using the path stored on the database, I used a DataRenderer to do that, and here is my code for Renderer and the DataGrid.mxml
CourseGrid.mxml

Result :
Problem :
How can I access to the path of the image, I tried to write "data.img" instead of "data" as img is the name of the column in the database that stores the path but it wasn't successful.
I know that it not complete statement "data" because "data" is a reference to what the DataGrid provides of information that gets from the (CreationComplete) event.
Question :
- Can you please help me with this so I can complete displaying images by accessing to what is on the column in tha DB so I can manipulate my datas that is stored there ?
==> I still have some questions about the buttons to update and delete datas fomr the DataGrid, but, until now I need to access successfully to the photo and display it
Thank you,

Anyone that can help me with this ?
Please, try this with me, I'm asking Flex developpers this might be easy for you !
It's just question of how to access the string stored in the variable "data", when I used XML I just type the path to the repeated element like this :
XML file :
XML File
<parent>
<child>
<repeated_child></repeated_child>
<repeated_child></repeated_child>
<repeated_child></repeated_child>
</child>
</parent>
I used a Model as a reference to the xml file
and an arrayList as a container of the repeated child
I just write in the code "data.parent.repeated_child" to access the text in the "repeated_child"
and here is the code, that I implemented to generate videos from xml file to display a video play list
Video Playlist code(extract from XML file "data.xml")
<fx:Declarations>
<fx:Model id="model" source="assets/data.xml"/>
<s:ArrayList id="products" source="{model.video}"/>
</fx:Declarations>
<mx:List dataProvider="{products}" labelField="title"
change="list1_changeHandler(event,List(event.currentTarget).selectedItem)" x="103" y="77" height="350" width="198"/>
That was my goal to do that with the database.
Please help me
If you have other solution I still need it.
Thank you,
