Once in a while, my kids get to my IMAC and do things I have no idea how. In this case, my iPhoto library is missing. It looks like a brand new iPhoto library since there is no trace of my photos or albums. This has happened before where I found exclamation marks which is was able to fix. In this case, I don't see the iPhoto library in the trash where it was last time. Any assistance where to start looking would be greatly appreciated. Thanks !
