Most of you have probably witnessed Servers advertising their companies or other companies via banners on the map. I know for a fact this was possible in 1.6 but I'm not sure about Source.
Over at ampednews.com we are hosting an All-Star Source match, with 5 of the best players of the East vs. 5 from the west. We wanted to help endorse our sponsors with in-game banners within the map. If any of you guys know how this could be done please help us out
