CLIENT_IMAGE.WRITE_IMAGE_FILE(vFile_Path, vTyp,'SD_DOCUMENT.DOCUMENT', NO_COMPRESSION, original_depth);What is the value of vTyp?
According to the Help these are valid values:
The file type of the image: BMP, CALS, GIF, JFIF, JPEG, PICT, RAS, TIFF, or TPIC.
So, try to use JPEG in case you used JPG.
Oh, and also try to specify the file type explicitly when reading the file. There is a mismatch for JPG, though, in the 10g documentation (I don't have 11g):
The valid image file type: BMP, CALS, GIF, JFIF, JPG, PICT, RAS, TIFF, or TPIC. (Note: File type is optional, as Oracle Forms will attempt to deduce it from the source image file. To optimize performance, however, you should specify the file type.)

I tried and I have no luck.
The image-field in the forms cannot have the JPG-Filetyp-property. It is missing in the list of values.
So my form transformed all images to tiff, regardless of which type the image is.
Perhaps when storing the image in the database transformation take place too.
Maybe the conversion happens here:
CLIENT_IMAGE.WRITE_IMAGE_FILE(vFile_Path, vTyp,'SD_DOCUMENT.DOCUMENT', NO_COMPRESSION, original_depth);
Not sure, but the NO_COMPRESSION may uncompress the JPG (which would be the same as a TIFF). If you leave it out (it's optional), the original compression is probably used.
You can open the image file in an ASCII editor and check the header . It will show JFIF for a JPG file and II for a TIFF file.
thanks a lot.
I tried, but the image remained being a jpg-file.
In Forms 6i it is the same. I think it is caused by the property of the image-field. I choose tif. In the help-file can be read that the files will be stored with their given format. Only if the format is not recognized then it will be stored as a tif. So jpg is not recognized? Bmp-file in the same image-field for example is recognized and exported as bmp.
I cannot choose jpg to test whether this option is the problem, because jpg is missing in the list (also in forms 11G).
My solution is now to change the file-ending to tif, when exporting a stored jpg-picture. That works for now.
