Change the alert "<Anon Pic> Someone favorited <Submission> <Thumbnail>" to "<thumbnail> <Submission> became a favorite."
Gotta admit the current phrasing is a little bit creepy and the anonymous user pic doesn't really help. Just show the thumbnail of the submission and leave out "someone" and the anonymous user pic. Honestly, for a long time i thought it was just broken because of all the default user pictures.
