I have several commercial duplicate finders, but I can’t find one that 
I’m pretty sure I used to have for images, or at least I saw somewhere.

This one would examine the image itself, and if it found the same image but 
at different pixels (say, 400 x 800 and 800 x 1600), it would match these, 
with the goal to keep the largest file (in pixels).

Anyone know of one?
