They don’t appear to actually exist, at least not anymore. I think the underscore in the name may have broken the filename. Image:_006.jpg and Image:_Maltese Pea Cakes.jpg You can see them here: http://www.wikihow.com/Category:Unlicensed-Images

Deleted these! Mediawiki treats the “_” at the start as a space and trims it off, which means the images are actually present but just not accessible. I just have to look up the page IDs and delete them using those. Thanks.
