I don't think there is a 'skin' option, outside of hacking the source. There are a few options, which are selectable within the fe by pressing tab. The only other configurable is the format/type of images shown - ie: snaps vs marquees....but I've never gotten the images to show up. The template shows, but not the marquee images. I gave up long ago. MaLa has very little system over-head that I've seen with more options and has a gui to configure by.
