Forum Advertising Help!
 

I've seen another site running vBulletin v4 that has a advertising in a style that I'd like.

What I'd like to achieve is five ads below our Nav Bar that are displayed randomly.

Currently all five ads are displayed below the NavBar, but this is obviously using up a lot of room.

I can't seem to find a setting anywhere that allows me to set a random display.

Any ideas?
