I suddenly discovered that my Pictures folder (the one inside the Home folder) is gone after starting iPhoto and it gave me the error: "Your photo library was not found." I did a quick spotlight search and did not find the Pictures folder. It was not in the Trash or anywhere. I don't know how this happened, as I can't possibly imagine how the Pictures folder magically disappeared. I just imported a ton of pictures into iPhoto and finished organizing and labeling them. Please tell me I don't have to do it all over again!
