The major thing that's stopped me from using iPhoto regularly is the way it wants to handle the organization of my photos. I unchecked the Copy Files to iPhoto Library Folder option, so at least it doesn't do that anymore. But for some reason it still likes making copies of a few photos to put in the Modified folder in the iPhoto Library Folder. Firstly, I didn't even modify the photo (though I suppose it might be because I'd rotated it in Preview earlier?), but even if I had, is there a way to just have it replace the original? I have quite a few photos, so I don't want it making too many copies that will take up a lot of space. Thanks!
