Hi, I recently upgraded my parents' iMac from Snow Leopard to Lion. It didn't occur to me to back up their photo library before the update, and it now appears that their photos in iPhoto are gone. According to my mom, when she tried to open iPhoto after the upgrade, she received a message that indicated she had no library, or something to that effect. Their current version of iPhoto is '09 v 8.1.2 on Mac OSX 10.7.5. I opened the package contents to see if there was a master file directory for the originals and none could be found. My concern is that the OSX update, and presumably, subsequent iPhoto update resulted in a fresh install replacing the old directory. All other files that were previously on their computer are still there. Only the photos are appear to be missing. Does anyone have any insight into this issue, and hopefully, a solution to possibly recover any photos? Thanks in advance!
