Folks, iPhoto is just very buggy and cannot be trusted. Often when I go to import photos into it from my iPhone or Camera, I find that not all photos are transferred. Remember this before you go off and delete photos from your other devices. I will have to go and quit iPhoto, relaunch it and then try importing again with better success. I don't know why this happens but its scary to think that I may have lost a number of photos due to a VERY buggy program.
