Banner Rotator help

[rdcody]

Hey All,

I found the banner rotator code below somewhere today. It
works very well, except I would like it to rotate the banners in
the order they are listed in, instead of random.

I plan on having 10 or 12 banners eventually. Would
someone please tell me how to do this? I'm new to
Javascript, but willing to learn.

Thanks in advance,
Ron
