Hey everyone. Awhile ago I transferred and set it up so that my iPhoto library was on a external hard drive. I would like to undo what I did. I want to move my entire iPhoto library from the external hard drive that its on to my iMacs hard drive and keep it there. I need my external hard drive for something else and don't want to go out and buy one, and I have 600gbs free on my imac and my iphoto library is about 20gb's so I figure i'm good to do this. So how do I do it? Thanks ahead of time!
