The images you are seeing are thumbnails that the CAT programs embed. The actuals were stored outside of the database as a linked image.
The restored database's default folder (OPTIONS > DEFAULT FOLDERS) doesn't match where the images actually are. You will need to find the actual images and then update the folder (TOOLS > UPDATE PATH > IMAGE FILES).
