Adding a banner to main page

Hi,

I'm sorry for asking this because I know it has already been addressed. I have read other posts concerning this, but they are bit different from what I am looking for.

I have added a banner to my main page page and used the code for the banner system so that I am able to track the clicks. My question is, what would I need to do to have this area rotate other banners as well? I gave my banner a new group name but I am unsure how to have other banners from this new group show. What code etc. would I need to use to display this new group here?

If you wish to see what I am referring to, please visit my homepage. My site sells adult lingerie and other adult products so please be warned if you choose to visit.
