Adobe PDF files could be added as clickable images (of various sizes) that when clicked would open the .pdf file. Since the upgrade although .pdf files can still be uploaded, when using the add image wizard these files cannot be seen (referenced). If the code is put into the page directly, then the file and filename can be seen as if it is a missing image (red x) and is clickable and will open the .pdf. You can clearly see the problem on the page linked to below.

Pages made before the upgrade, operate as normal with .pdf files. However new .pdf files cannot be added using the add image wizard, as can be seen at the page link below.
