- Is a "view" on the photos in your library
- Think of albums as "Labels" in GMail
- many labels (albums) can point to the same e-mail (photo)
- you can create as many labels (albums) as you want
- deleting a photo from an album is akin to removing a GMail label from an e-mail -- that e-mail (photo) is simply removed from that view (label/album), but the e-mail still exists in your library
- deleting a label (album) does not delete your e-mails (photos); it only removes the association
- all of your photos
- deleting a photo in your library moves it to iPhoto's trash -- i.e., it still exists
So far, I hope the distinctions have been clear between deleting a photo in an album versus deleting a photo in your library. Once you have deleted a photo in your library (and it has been moved to the trash), you must EMPTY THE TRASH to permanently remove the photo from your computer. There are three ways to do this:
1. Use the main menu bar
a) click on "iPhoto" in the main menu
b) click on "Empty Trash"
2. Use the trash icon
a) look under "Recent"
b) right click on "Trash"
c) select "Empty Trash"
(Note: the icon will appear under "Recent" if you've recently viewed/emptied trash)
3. Use a shortcut
a) make sure you haven't selected any images anywhere
b) press shift-command-delete
