I imported a large number of photos to iphoto from my macbook HD, the"copy" box was not checked. Then because I'm short on HD space, I deleted the photos from my HD & emptied the "trash". Now I can see my photos in the PHOTO of iphoto, but when I try to add to an album or copy them, I get an error message "photo could not be opened because the original item cannot be found". Is there any way these photos can be recovered? I can still see them in iphoto, they must be stored somewhere...
