get WP-MulticolLinks to show images?

Hey, sorry if this has been asked for before, but I’m getting pretty desperate to have affiliates on my website to show up in two columns and I want the affiliate images I’ve added to appear instead of the link names.

I found this plugin: http://wordpress.org/extend/plugins/wp-multicollinks/
and it works pretty good, but it doesn’t seem to allow the option of showing images instead of link names. I really need to get this to work somehow. :S

Any help would be great.
