Advertising is a great way to add an extra revenue source to your site. As such, a fairly standard set of sizes has been created to prevent advertisers from having to "extreme-customize" their ads.
Please note: This comes directly from the Interactive Advertising Bureau (IAB). Schipul and Tendenci make no claims to the creation of this content, merely the dissemination of it. Check out the IAB!
