Program to find/delete duplicate photos

[bearfacekilla]

Does anyone know of a good application to find and delete duplicate photos. I'm trying to work with a massive photo library (40k+ images) and get rid of duplicates including thumbs created by Iphoto. I'd prefer freeware but am willing to pay if there is a particularly effective program. Thanks!

If you want more information, here is just one of many threads on this topic, found by searching the forum with MRoogle:

Try Gemini. I got it on the mac app store. Although it can't delete all the duplicate files, at least it shows you where they are.
