OK so my own iPhoto database doesnt have any dupes, but thats because I'm an organized bugger, but a friend of mine has tons of duplicates, and I have no idea how they got there, didnt want to ask.., but does anyone have a good tool or solution for removing exact matches of photos from iPhoto?
I haven't got round to it yet but I have a copy of Duplicate Annihilator to do this job. It looks promising but I think I will make sure I have a good back-up when I test it out. I would be interested in how you get on if you try it.
