At this time you can't do either. The block really just utilizes the built in Geeklog links system. I see a lot of sites using logo's, and I thought about adding in that functionality. In doin so, I'd have to create some separate tables or expand on the tables geeklog uses for links (separate tables would probably be best).
I don't have any plans for upgrading it right now, but if I get enough people requesting that type of stuff maybe I'll expand on it. ---Paul 'T1Pimp'
