I actually have had the list of filetypes on my w:c:wolfenstein changed to include BMP and TGA (though TGA is broken so I regret that). Just a simple Special:Contact/general will do it.

They may notice that it's to enable fonts and give you a lecture about it or something though. Fonts tend to be copyrighted and some of them you're supposed to pay to use. The font in question is freely available from the authors and this page says that no further permission is necessary to use it, so you should be all right.
