Every time I try to "share" (move them out) my iPhoto files and move them out of iPhoto to another folder, if the numbers happen to be the same from a previous time, it will tell me they already exist and do I want to replace those photos with the new ones. The problem is they are not the same image, and I don't want to loose the older ones by replacing them with the new ones. How do I avoid this? I've tried to rename them in iPhoto and it still says they are the same number. Appreciate any help anyone can give for this issue. I'm trying to organize my thousands of images.
