I would think this should be pretty straightforward. I can see where the the images and theme is set, it should be a simple edit of the theme file or replacing images with a symlink to a single transparent image? Some day, I really hope to have the time to submit some clean patches, but until then, anybody interested in doing this one, it's appreciated! I didn't see anything on preware to do this, forgive me if it already exists, and if so, can you point me to it?
