These three files either need to be updated with the default skin, or get deleted if they aren't used.
I'll get to updating those, seeing as they are used. And for the record, that was the default skin at the time, but fair enough. :P
Edit: I take that back,
File:VIP_remove.png was not used due to concerns regarding space, and it was instead stated that the "Add" button is replaced. As such, this file can be deleted.
I gotta say, it feels good to get back to editing. c:
