A while back, I read somewhere that creating a new library (or something like that?) in iPhoto would help me with an iMovie problem I was having. It was a while ago so I don't remember what I did exactly, but I think I created a new library or something. Now when I open iPhoto, it shows none of my pictures even though they are still on the computer (I can see them in the hard drive). How do I make it so these photos show up in iPhoto again?
