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.

Display BLOB Images from a SQL Server DB

I am using Crystal Reports X and SQL Server 2000. I have a table (TABLE_PICS) that contains images (the images are stored in the DB. I have another table (TABLE_NAMES) where each record references its related image by an ID.
What I want to do is create a report where I display each record from TABLE_NAMES with their associated TABLE_PICS images.
I created a report, and the link is valid, but the report only displays a thumbnail and the name of the image.
1. Can someone tell me how I can get the actual images to appear?
2. I would prefer the images not be stored in the DB. Can someone tell me how I can get the images on the report as explained above, without the images being in the DB.
TIA,
Jack

[Forum FAQ] How to display an image from Http response in Reporting Services?

Question:
There is a kind of scenario that users want to display an image which is from URL. In Reporting Services, if the URL points to an image file, we can directly display it by typing the URL in embedded image. However, some URLs are just sending Http requests
to server side, then redirect to another position and the server will return the image. For these kind of URLs, Reporting Services can’t directly render the image from Http response.
Answer:
To achieve this goal, we can add custom code into the report. Pass the URL as argument into our custom function so that we can create HttpRequest and get the HttpResponse. Then we can use custom function to return the Bytes() from the HttpResponse and render
it into an image in report.
Ps: In Reporting Services, it only support drawing Bytes() array into image, so we need to have our custom function return Bytes array.
Add the assembly and custom code into the report.
Public shared Function GetImageFromByte(Byval URL as String) As byte()
                Dim photo as System.Drawing.Image
         Dim Request As System.Net.HttpWebRequest
       Dim Response As System.Net.HttpWebResponse
              Request = System.Net.WebRequest.Create(URL)
                 Response = CType(Request.GetResponse, System.Net.WebResponse)
             If Request.HaveResponse Then
                  If Response.StatusCode = Net.HttpStatusCode.OK Then
                       photo = System.Drawing.Image.FromStream(Response.GetResponseStream)
                 End If
            End If
              Dim ms AS System.IO.MemoryStream = new System.IO.MemoryStream()
             photo.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg)
                Dim imagedata as byte()
                imagedata = ms.GetBuffer()
                return imagedata
End Function
Grant the permission for assemblies.
Go to:
C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\PrivateAssemblies\RSpreviewPolicy.config
C:\Program Files\Microsoft SQL Server\MSSQL\Reporting Services\ReportServer\rssrvpolicy.config
Give “FullTrust” for Report_Expressions_Default_Permissions.
Insert an image into report.
Expression:
=Code.GetImageFromByte("https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcSrVwPoAtlcA2A3KaiAJi-XjS4icr1QUnKYr7uzpX3IL3g2GPisAQ")

Hi, I'd like to display a dynamic image from the web inside a JLabel or any other swing component it could work in. I've been looking on the Swing tutorials and others forums, all I can have is that a JLabel can load an Icon object, defined by an image URL, but can this URL be like "http://xxxxx/image.jpg" somehow or can it only be a local image URL?>
I do not know why you start talking about an image on the web then go on to show concerns about whether it will work for a 'local' URL.
But perhaps this answer will cover the possibilities.
So long as you can from an URL to the image, and the bytes are available for download (e.g. some web sites wrap a direct call to an image in HTML that embeds the image), the URL based icon constructors will successfully load it.
It does not matter if that URL points to
- a web site,
- a local server ('localhost'),
- an URL representation of a File on the local file system, or
- it is inside a Jar file that is on the application's run-time classpath.
How you go about forming a valid URL to a 'local resources' (or indeed what you regard as local resources) is another matter, depending on the form of the project, and how the resources are stored (see list above).
Probably the main reason that examples use images at a hard coded URL on the net is that it makes an 'image example' self contained. As soon as we compile and run it, we can see the result. I have posted a few examples like that on these forums.

How to display BLOB images from the Oracle database within Crystal

Let's say a have the following table
IMAGES
========
DOC_ID NUMBER
DOC_NAME STRING
DOC_IMAGE BLOB
The BLOB field can have any type of document: PDF, email, WORD, EXcel, etc. I would like to present the DOC_ID and DOC_NAME and let the user click any of them. Once the user clicks the document stored in the database as BLOB, it is rendered using the default application associated to the extension. For example if the file name is ABC.XLS open MSExcel if the file is abc.pdf open Acrobat.
I am using Crystal2008 and evaluating Crystal 4.0
Does this requires programming?
Thanks!!!

Hi
Crystal is a reporting tool and you canu2019t execute any code except free hand SQL. When you pull any BLOB fields in crystal, it takes as a picture field and if that field contains image only it will display in your report.
If you have any information other than image, it will not display any info in the report.
If you want to insert Word , PDF and Excel then you will have to insert as ole object and can manage with location of the files.
Thanks,
Sastry

Displaying BLOB (image) data in BI Publisher Report - E-Business Suite R12

Hi All,
As part of E-Business Suite R12.1.3 upgrade, I need to develop a PO printout report using MS Word BI Publisher Desktop Plugin. The report needs to include images (signatures) from the database based on requisition approvers.
How can I build a custom view and a template to use with an RTF report and include dynamic images in it? Is it possible?
Thanks,
Sinan

yes, it is possible
look at Inserting BLOBs into your report
steps:
- create data definition with query with blob (say image) in xmlp
- create empty template and load it into xmlp resp
- create concurrent
- run concurrent
- save xml
- use BI Publisher Desktop with xml data for construct template layout
- load template layout to xmlp resp
another way
- if image in os you can try to use OA_MEDIA + image name

Display BLOB (image) column in (interactive) report

Hi,
I have a field called "picture" in my table "details" which is of type BLOB. i also have a field for "MIMETYPE" and "filename"
i additionally have a "name" and "description" columns which i need to display along with the picture as columns in a report (preferably interactive).
i have also modified the BLOB display format as per
http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/apex/r31/apex31nf/apex31blob.htm
what i am missing is the correct query. if possible, i would like to control the size of the picture rendered within the report like say 40*50.
I have also referred to the thread
APEX 3.1 Display BLOB Image
But i don't know how to place the
dbms_lob.getlength("BLOB_CONTENT") as "BLOB_CONTENT"
in my query.
The above also makes the report column as of type "number". is this expected?
Any help would be much appreciated.
Regards,
Ramakrishnan

You haven't actually said what the problem is?

Something like:

 details
if possible, i would like to control the size of the picture rendered within the report like say 40*50.For images close to this size it's easy to do this for declarative BLOB images in interactive reports using CSS. Add a style sheet with:
.apexir_WORKSHEET_DATA td[headers="PICTURE"] img {
display: block;
width: 40px;
border: 1px solid #999;
padding: 4px;
background: #f6f6f6;
}where the <tt>PICTURE</tt> value in the attribute selector is the table header ID of the image column. Setting only one dimension (in this case the width) scales the image with the correct aspect ratio. (The border, padding and background properties are just eye candy...)
However, scaling large images in the browser this way is a huge waste of bandwidth and produces poorer quality images than creating proper scaled down versions using image tools. For improved performance and image quality, and where you require image-specific scaling you can use the database ORDImage object to produce thumbnail and preview versions automatically, as described in this blog post.

I have done exactly that in one of my applications.
I have extracted the image from the database as a byte array, and displayed it using a servlet.
Here is the method in the servlet which does the displaying:
(since I'm writing one byte at a time, it's probably not terribly efficient but it works)
 private void sendImage(byte[] bytes, HttpServletRequest request, HttpServletResponse response) throws IOException {
 ServletOutputStream sout = response.getOutputStream();
 for(int n = 0; n < bytes.length; n++) {
 sout.write(bytes[n]);
 sout.flush();
 sout.close();
 }Then in my JSP, I use this:
<img src="/path-to-servlet/image.jpg"/>
The name of the image to display is in the URL as well as the path to the servlet. The servlet will therefore need to extract the image name from the url and call the database.

Displaying BLOB image by using ADF Faces

Hi all,
I digged the forum but couldn't find any satisfied answer about displaying BLOB images by using ADF Faces.
I have insterted POJO object to Oracle database but couldn't find any way to display blob (in java byte [] ) data in POJO.
I have read the POJO object from database which contains two field; one of them is id field and other is BLOB data which holds GIF or JPG image and I want to display this image another page which contains also other fields / records ...
thanks for your answers

This thread at Sun : http://forum.java.sun.com/thread.jspa?threadID=513804&messageID=2445090
talks about two options for creating a graphicImage jsf tag. (img tag)
1. Make the img tag url refer to a servlet (instead of a static image file)
2. Embed the image into the tag as inline base64 encoded data.
2a. Use an <Object> tag with inline data.
1. Looks a bit complex for a simple problem.
2 and 2a don't work with some browsers.
- And I've not yet figured out how to hook into the ADF Faces table-rendering logic to get it to add my image column. My table binds to a collection DataControl, [which in turn retrieves from a findAllItems call on a session facade, which uses my domain model, and wraps up access to a TopLink pesistence layer]. The framework just ignores my byte[] attribute when creating the jsf table from the DataControl. All string, int etc. attributes get represented correctly in the jsf table output.

Displaying blob image using adf

Hi ,
We are using adf in our application. We have to disaply blob image from oracle data base on the adf jspx page.This jspx page consists of 2 jsff files.
I have created an httpservlet and called on the source parameter of image this httpservlet with binding similar as below:
source="/httpServletName?id=#{bindings}}"
I am able to display the image.
But my concern is that I am using iterator for displaying images as there can be multiple records in the table but for every recoed I am getting same image. Please suggest how can I display multiple images coming with respect to various records of data base.
thanks & Regards

Hi,
After attempting the solution given above also I am getting the same issue.
On the jspx page I want to show Imageid, imagedescription and photo .
I have 4 records coming from database on the jspx page. I have found that all the data (imageid, description) is first displayed on the jspx and then control gets transferred on the ImageServlet only once and in request.getParameterMap() I get only one "ID" value i.e. the ID value of last record (4th record) coming from data base and hence in all the 4 records on jspx I am getting the same image (i.e. the image in the 4th record of db). Please help me to proceed on this issue.
On jspx, I have given image source value as :
<af:image shortDesc="image"
id="image1"
source="/imageservlet?id=#{bindings.Id.inputValue}}"/>
Thanks

Problem with displaying BLOB images on JSP page using a servlet

hi. I have a big problem with displaying BLOB images using JSP. I have a servlet that connects to the oracle database, gets a BLOB image , reads it, and then displays it using a BinaryStream. The problem is , this works only when i directly call that servlet, that is http://localhost:8080/ImageServlet. It doesn't work when i try to use that servlet to display my image on my JSP page (my JSP page displays only a broken-image icon ) I tried several coding approaches with my servlet (used both Blob and BLOB objects), and they work just fine as long as i display images explicitly using only the servlet.
Here's what i use : ORACLE 10g XE , Eclipse 3.1.2, Tomcat 5.5.16 , JDK 1.5
here is one of my image servlet's working versions (the essential part of it) :
 BLOB blob=null;
 rset=st.executeQuery("SELECT * FROM IMAGES WHERE ID=1");
 while (rset.next())
 blob=((OracleResultSet)rset).getBLOB(2);
 response.reset();
 response.setContentType("image/jpeg");
 response.addHeader("Content-Disposition","filename=42.jpeg");
 ServletOutputStream ostr=response.getOutputStream();
 InputStream istr=blob.getBinaryStream(1L);
 int size=blob.getBufferSize();
 int len=-1;
 byte[] buff = new byte[size];
 while ((len=istr.read( buff ))!=-1 ) {
 ostr.write(buff,0,len);
 response.flushBuffer();
 ostr.close(); and my JSP page code :
<img src="/ImageServlet" border="0" > If you could just tell me what i'm doing wrong here , or if you could show me your own solutions to that problem , i would be very greatful ,cos i'm realy stuck here , and i'm rather pressed for time too. Hope someone can help.

I turns out that it wasn't that big of a problem after all. All i had to do was to take the above code and place it into another JSP page instead of into a servlet like i did before. Then i just used that page as a source for my IMG tag in my first JSP. It works perfectly well. Why this doesn't work for servlets i still don't know, but it's not a problem form me anymore . Ofcourse if someone knows the answer , go ahead and write. I would still appriceatte it.
here's the magic tag : <img src="ImageJSP.jsp" border="0" > enjoy : )

Hi
*Play all resp one chapter at a time*
Play All Button
1. There are NO - Play All - button in any version of iDVD
2. It can be faked in several ways
• Easies and most fault proof way is to make a doublet movie containing All and with
Chapters set to match. It will take up x2 space but is easy to understand and produce.
• It's said that one can put all movies into a Photo/SlideShow and this will also
give the function of a Play All button - Never tested though.
Mike Evangelist1
You might be able to get close to what you want by using a slideshow in iDVD. (It's not widely known, but you can put videos in a slideshow.) If you set the slide duration to manual, playback will pause after each movie/slide, and you can continue with the 'next' button.
3. Using another program to do this eg. Roxio Toast™ where there ia a Play All button option.

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.

How can I display an image from a shared-network folder?

Hi
Does anyone know how I can display images from within APEX that are found outside the database? What configuration have I missed?
Within Windows-Internet-Explore I can access the following image using the below URLs, BUT I cannot access it from within APEX?
What do I need to do so APEX can display theses images from our internal shared network folder?
both these URLs work within Firefox (but on APEX):
\\Saremote\UPDOWNFILES_DIR\polk_insight.gif
file://///Saremote/UPDOWNFILES_DIR/polk_insight.GIF
So within APEX I have created a "display as Text' Item that works with this "amazon image" syntax:
{lessthan} IMG SRC= {doublequot} http://g-images.amazon.com/images/G/01/associates/navbar2000/logo-no-border(1).gif {doublequot} {greaterthan}
BUT sadly not with my image:
{lessthan} IMG SRC= {doublequot} file://///Saremote/UPDOWNFILES_DIR/polk_insight.GIF {doublequot} {greaterthan}
Any ideas would be appreciated.
Thanks
Steve

If you have a local html file, or open an image locally from the menu, then yes, it works, but with web pages that are served from a remote location (web server), security kicks in and prevents the web page from accessing local files (and files on a networked drive).
you will either have to put the image on the web server and access it through http, or you can load it into the database/workspace images and access it that way.
