good way to show random advertiser banners?

[simple_john]

ive got 4 or 5 advertisers on my site... presently i have a small banner (180*40) w/a link for each advertiser added to the header,

This works fine: www.mytractorforum.com

but when/if i get a few more advertisers, i dont want the header all gunked up with so many banner images

i was thinking of possibly just showing 3 banners at a time and somehow alternating the banners on a random basis.. every 15-20 seconds or so...

anybody do this? and care to show me ?

or anyone have a better example of how to show more than a few banner ads for advertisers?


i did not really want to do a sidebar...





thanks for any input...
