How to combine Image w/ description tooltip and swap image restore in one page?

[dongastone]

1) Script Title: Image w/ description tooltip

2) Script URL (on DD):
http://www.dynamicdrive.com/dynamici...agetooltip.htm

3) Describe problem:
Hi there, i just use the Image w/ description tooltip script, and it works great until i add behavior "swap image" on one button?
So this is the page before i assign behavior on buttons:

and a want to make buttons "back" and "next" to change colors...

Thank you

P.S. If the page with tooltip script is in <iframe> everything works, but if there is a way to make it work on one page - will be great
