Client_Image.READ_IMAGE_FILE problems

Question

Hi, I have search all over OTN and the web and can't seem to find a solution to my problem. Im using Forms 10gR2, and am trying to display a TIFF image in a form. I am not getting any errors, its just not displaying the image at all.
I have the images stored in C:\temp\0-GRAPHICS\. I have looked at the webutil.cfg file and updated it with the following:
#NOTE: By default the file transfer is disabled as a security measure
transfer.database.enabled=TRUE
transfer.appsrv.enabled=TRUE
transfer.appsrv.workAreaRoot=c:\TEMP
transfer.appsrv.accessControl=TRUE
#List transfer.appsrv.read.<n> directories
transfer.appsrv.read.1=c:\temp
transfer.appsrv.read.2=c:\
transfer.appsrv.read.3=c:\DevSuite10_1_2
#List transfer.appsrv.write.<n> directories
transfer.appsrv.write.1=c:\temp
transfer.appsrv.write.2=c:\
transfer.appsrv.write.3=c:\DevSuite10_1_2
When I run the code, i get no error, it seems to work, just no picture displayed. Here is my code
When-Button-Pressed trigger:
DECLARE
tiff_image_dir VARCHAR2(80) := 'C:\temp\0-GRAPHICS\';
  photo_filename VARCHAR2(80);
BEGIN /* ** Set the message level high so we can gracefully handle ** an error reading the file if it occurs */
  :CB_PLATE_TIFF.ESL_NUMBER := :UNION_HDRS.ESL_NO;
  :CB_PLATE_TIFF.PLATE_NUM := :EIF_ONE_PPB.EIF_PLATE_NO;
  :System.Message_Level := '25';
  /* ** After fetching an employee record, take the employee's ** Userid and concatenate the '.TIF' extension to derive **
  the filename from which to load the TIFF image. The EMP ** record has a non-database image item named 'EMP_PHOTO' ** into which we read the image. */
  photo_filename := tiff_image_dir||:CB_PLATE_TIFF.ESL_NUMBER||'\'||:CB_PLATE_TIFF.PLATE_NUM||'.tif';
  /* ** For example 'photo_filename' might look like: ** ** /usr/staff/photos/jgetty.tif ** ------ ** ** Now, read in the appropriate image. */
  client_image.READ_IMAGE_FILE(photo_filename, 'TIFF', 'CB_PLATE_TIFF.IMG_PLATE');
  IF NOT FORM_SUCCESS THEN
  MESSAGE('The TIFF file '||:CB_PLATE_TIFF.PLATE_NUM||'.tif does not exist.');
  END IF;
  :SYSTEM.MESSAGE_LEVEL := '0';
  GO_BLOCK('CB_PLATE_TIFF');
END;
Am i not initializing the tiff_image_dir properly? Thanks for any help.

Without actually being able to test your form, my only remaining guess is that the version you are using has a defect.  Since you did not mention exactly which version you are using, I will guess and say that you are using an unpatched version.  Please ensure that you are using Forms 10.1.2.3.  If you are not using this patch version, I recommend you download and install it.  You must have a current MyOracleSupport (and Support) account to do so.  The patch ID number is:  5983622
Also, since version 10 is no longer entitled to Premiere Support, it might be a good time to consider upgrading to the latest release, 11.1.2.2

Installing WebLogic Server 10.3.6 is a prerequisite to installing Forms/Reports 11.1.2.2, so be sure to download and install it first.  Be sure to review the product documentation before installing any software.
