iPhoto: DELETING PHOTOS TRICK

By now you already know that if you delete a photo from an album, it just deletes it from the albumthe original file is still intact in your Library. So, if you really want that photo deleted that you just removed from your album, you have to now click on the Library in the Source list, find the same photo, and remove it there as well. That is, unless you know this shortcutjust click on the photo in the album, and press Command-Option-Delete. This removes it both from the album and the Library at the same time.
