Photos disappeared from some albums
I have many albums and folders, including one folder with 94 albums of photos for my website. When adding a photo to one of those folders yesterday, ALL the photos in ALL 94 of those albums disappeared. How can I get them back? Other unrelated photos in different folders and albums are still visible. I looked at Time Machine but only saw iPhoto. How is it possible to get photos from that backup and to have those photos sorted into the proper albums?
