scrolling sponsor banner

Hi,

I have Dreamweaver 4 and Fireworks 4...for a website I'd like to have a window where our sponsors logo's rotate through every 10 secs or so...thought dynamic layers were the answer but can't seem to get it to work per the instructions in the manuals....have 4 images...can someone help or direct me to a resource.

Thanks in advance

Cheers
Brian
