The JSMO Kewl Tool is an excellent script by Bill James. "JSMO" stands for "JavaScript MouseOver", and the script will write your JavaScript for the popular mousovers, aka rollovers or hover buttons. You simply create an "off" and an "on" button, type in the details, and the script is created ready for you to copy and paste into your page.
