you will have to do what you did with your gallery island with a custom island, but that is easy..

for each sponsor / image combo... put

HTML
<div class="sponsor_side_link">
  <a href="http://sponsor_supplied_link.com">
    <img src="http://www.prosanddrags.com/forums/gallery/28/thumbs/49.jpg />
  </a>
</div>

change the sponsor link and the thumb from the gallery for each new sponsor you want.

you can style the sponsor_side_link class with css too...
