Plugin widget to display author images on sidebar?

Hi – I’m looking for a widget that I can use to display on the sidebar a column of small static banners that link to my author’s websites (as an incentive for blogging).

I’d just edit the sidebar and put the images in there manually, but I’m using Sidebar Widgets and I want the images to display under the category block – this doesn’t seem possible if the author banners are not a widget themselves.

Anywhoo – does anyone have an ideas for how I can accomplish this?
