Little modification to scrollable iframe

[maxi]

1) Script Title:
Scrollable iframe

2) Script URL (on DD):
http://www.dynamicdrive.com/dynamicindex17/iframescroll.htm

3) Describe problem:
How can it be modified so that it scrolls horizontally and onClick, not onMouseover, and displays more than one box?

Thanks

Or well, like a featured content slider (http://www.dynamicdrive.com/dynamicindex17/featuredcontentslider.htm) but with more items showing.
