I have a client who would like me to create a portfolio for him displayed in a manner similar to the one on this page: http://www.gerarddesign.com/portfolio.shtml.

I know how to create an animation where the visitor can click on the small image and a new frame appears with the large image on the right, but I cannot figure out how to have the small image change upon hover-over before the visitor clicks on it.

Thanks in advance for your help.
