All of a sudden my iPhoto library is missing. iPhoto can't find it, and it is not located in my pictures folder anymore. How can this happen? I googled this problem, and it seems it has happened to people occasionally over the years. Luckily, I have backed up my hard drive, but how can an entire 12 gb iPhoto library just disappear?
The computer works just fine. The iPhoto library is the only thing that disappeared. My friend plugged his iPhone into my computer to charge it, and when I opened the computer, I was asked something about which iPhoto library to sync with it. That might have something to do with it.
