It would be possible to check for byte by byte comparisons, by using "FC" a "dos" utility available on all windows systems to delete duplicate files no matter what their name, I'm sure that linux/unix has such a utility but I can't remember it's name right now. There are several problems to overcome, none of which will solve the most important one. There must be a way for the computer to recognize a duplicate image, not a duplicate file. It's easy enough to write something that will delete files with the same name in the same or different directories. A bit more complicated to recognize and delete duplicate files with different names, (and this begins to become time consuming), but I know of no foolproof method to automate deletion of duplicate visual images, at least not with the computing power available in a PC or Mac.
