md5 is another tool like cksum, but the checksums it creates are more  
unique than that of cksum.

David's method will work for everything, not just image files.

What's cool about GraphicConverter, though, is not only that there's  
no programming on the user side required. GC can also find close  
duplicates. So if you have the same picture in different resolutions,  
GC can find it. If you have applied a softener to one picture, you  
can still find it.

Oh, and two more things about GC: a) I am in no way affiliated with  
Lemkesoft, just a happy user. b) This feature happens to have been  
added on my request, just to give an example of how responsive the  
author is.
