Duplicate file finder

Can anyone recommend a good free duplicate file finder.
I have hundreds of duplicate photos and have decided its time for a clean out.
Thanks

I like Twins. So easy a caveman (or woman) could do it.

Thanks for the reply but i was looking for a free app as I would probably only use it once.

Hi Docx - I don't have a 'free' recommendation, but as a side question, I was wondering whether this could be done from the 'Terminal' w/ a command line set of instructions or Apple scripting - did a quick search and found some information, such as this LINK. I'll be curious if some of our UNIX gurus will 'chime in' w/ advice on this approach - NOW, I'm a newbie to the 'Terminal', so not necessarily suggesting this approach for you, unless you're comfortable w/ this route - good luck!

Thanks again RadDave.
Using a script looks a little daunting at the moment. I think I will keep looking for App at the moment.

Gemini is not free, but has been getting good reviews. The price has dropped from $9.99 to $6.99 and is available from the iTunes Store..
