For clarification of the following post, here's a photo page, and here is an actual photo.
During the issue a while back the photo pages/actual photos were deleted, but the photo pages were restored. SP does not keep a record of the actual deleted photos, but does keep a record of deleted "photo pages". So if for example you have a photo page with votes/comments/ect but is missing the actual photo, you can replace the missing image on the photo page via the edit page link followed by the browse button and then submitting it.
