Images not displaying

   I have an app (using version 7.x) which runs continually on a server and produces pdf's without any problem. 

However, every so often it fails to prodcue some of the images, images it has handled fine until a particular point after which they never get included in the output. This could I suppose be a memory issue, but I'm not sure. I would very much like to be able to test for this problem but not being able to reproduce it in the devlopment environment it is tricky. 

Any ideas waht I could test to see if teh image has been included? the code for merging them is fairly basic:

 ImageFile := PdfLibrary.AddImageFromFile(ifn, ImgOpts);

 if PDFLibrary.PageCount > 1 then
    PDFLibrary.SelectPage(PDFLibrary.GetFormFieldPage(fldID));

 PDFLibrary.FitImage(uLeft, uTop, uWd, uHt, 1, 1, uRotate);

Thanks

Russell

	1. Have you monitored the memory usage on the Server to make sure all memory is being freed. If there is a memory leak then memory usage will increase gradually. 2. One option may be to automatically close down your app after a set number of pages or time and then have it automatically restart itself. 3. I assume you are checking the return values. ImageFile would equal 0 if it failed. Andrew.
