On Links2 there was a mod that allowed you to attach an image to a link - from the admin area ONLY. Is there a mod like this for SQL?

I have some affiliate links that track the impressions of their link using a 1x1 pixel image. So it would be basically invisible.

Again, I just need to figure out how to add the URL of an image to the link when it is printed out, and it only needs to be from the admin page.

Thanks for any help,

Chad
