app for mac to delete duplicate photo files

[soppypreggyloon]

is there an app for my macbook that will go through the millions of photos and delete the duplicates?

there are too many to do it myself!

TIA! :)

TidyUp! is brilliant:

it costs a bit but it's worth it.

If you've got an older Macbook then there's a great free app called iPhoto Diet which you can get here www.rhythmiccanvas.com/software/iphotodiet/

However if you've got Snow Leopard (OS 10.6) and/or iLife 11 then it apparently doesn't work.

However there is an app I've heard of but never used that is only $8 that claims to do the job
