Offensive images in article histories
OK, everybody knows that featured articles are frequently vandalized, and one of the more common infantile tricks is to insert some image, usually a penis, in the featured article.  These are always quickly reverted, but I wonder why the offensive images remain in the article's edit history.  For example, somebody inserted a photo of masturbation in today's featured article on Joseph Smith, and it is still visible when you get back that far in the "compare selected versions."  Isn't there a way to just indicate what the vandal did (as is done with the ID of the image), and to remove the actual image itself from the article's history?  In general, that's a big problem with these "selected versions" in the article historythat things like this remain and aren't completely removed/disassociated with the article.
