Re: iPhoto not asking about duplicates on importing

i am using PhotoSweeper .It can also identify duplicates in different resolutions or edited duplicates, and lets you control the rules for marking a photo for removal - the newer one, the smaller one, the one without captions or keywords, etc.

You're welcome. I am sorry, it was no better news. 🙂
