sponsor widget

Hello,

I have a website that has sponsors on it on the bottom on the home page and on the sidebar on all other pages.

This is the site: gpe.fs.um.si

What do I need?

The sponsors are a .png image made in gimp, and if you click on one of them they redirect you to their website.
The links are made with this:

<map id="ImgMap0" name="ImgMap0">
	<area alt="" coords="424, 2, 825, 118" href="http://www.akrapovic.com/" shape="rect" />

I need a plugin, that will make it easyer for me to add sponsors, with some kind of a grid gallery or something… It has to be faster..

Thanks!
