go into thier banners section thru the links on the bar menu at the webmasters page, pick the type you want...then pick the site you want to promote from the buttons there...they will load..right click on the one(s) you want to use and save them to your hard drive...upload them to the folder you want to use them in and link them via your sponsor code and a img src tag bringing up the banner...
if this confuses you, just to go this free site of mine
