Tabs Menu (mouseover) Image Rollover?

Script: Tabs Menu (mouseover)
http://www.dynamicdrive.com/dynamici...bmouseover.htm

Hello,
I am using the above script with Images instead of HyperText for both the top level menu and the sub-level menu. Everything works fine. I would like to know if there is any way I can have the images respond to a rollover command, so that when I hover over the image it can change to a different image (change of color or highlight).

I've tried including onMouseOver and onMouseOut commands within the sublevel IMG SRC tag, but it didn't work.

Here is a link to the page I've built (Roll over CHINA and NEW YORK in the menu):

Many thanks,
