Duplicate Images

Looking for a GOOD duplicate image detector.

Currently using DupDetector; it's good, but it doesn't compare gifs (I have to go through all my pics to rename them to .pngs which can get annoying) and of course, can't compare animated gifs, and it often miscounts files in folders even when ALL of the files are compatible with DupDetector (the folder I'm trying to dupe detect only has PNG, JPG, and BMPs, all supported, and somehow DupDetector is undercounting the files by 250 images).


So... what do you guys use?

I don't get obsessive compulsive over my 120,000 image collection of shitting dick nipples hentai and just use CloneSpy to get hash duplicates.
