It would be nice if default gravatars (identicon, etc) are allowed even when the user unticks the "If you have a valid Gravatar associated with your e-mail address, use it for your user picture." checkbox.

It is a "default" image anyway and would enable the site to still have the randomly generated avatars even if the user unticks that (giving consistency, otherwise, users unticking that and not uploading a picture will either not have a picture or all have the same default one).

thanks
