Somehow my IPhoto library got corrupted. All the thumbnails were there as well as the original photos, but I couldn’t edit or play slide shows. I went to an Apple Genius Bar, where they created another new library and imported my photos into it. I still see my original IPhoto library as well as the new one. But I look inside the new IPhoto library (via view contents) I also see my old library there as well as another library that seems to have created itself. Question, can I delete the original corrupted library? Can I delete the old and self created libraries from within my new IPhoto library?
