Hi I have 7,000+ photos in my iPhoto library, many of which have been painstakingly edited. However, when I noticed yesterday that pictures I had deleted (and emptied from the iphoto trash) have reappeared in the library under the relevant 'Events' folder. Why oh why oh why? I have spent six hours already redeleting and editing. Why did this happen? How can I repeat it from happening again? Do I need to "rebuild" my library by holding down the command + option keys when opening iphoto? Any help gratefully received.
