Illusion--I've tried that and the background image seems to be lighter than the items in the foreground. Rolfi--I'd crank down the transparency settings for the .rsr thumbnails, and use Phil's solution. Transmapped hair does not have the same detail at thumbnail size. So I'd make it a little more solid (set transparency to zero) so the figure doesn't appear bald with a halo of gnats for the library images.
