I know there are lots of programs that find duplicate images on your PC, but does anyone know of a program that finds specific duplicate images? I have 300,000 images of one sort or another (or so my current software tells me, and that includes backups and yes - I do need to cull them). Running a program to find all duplicates finds a zillion matches. However, if I have several versions of one specific image I have no way of finding just those specific duplicates without finding *all* duplicate images!

I'd just like to give the software one image and tell it to go find all the other versions of that one image rather than all duplicates. Is there such a program?? I can't find anything via Google so far.
