I used 5 jpg images that are 150 wide by 96 high and set the applet width and height to 520 x 270. You can use any size images you want to use, different sizes or not. One thing to remember is to increase the applet width and height if you use larger images.
Each image can be linked to a different url. In this example all of the applet urls lead back to the index page of this site. There is a lot that can be done with this applet. Intel has discontinued the download page for their applets, so email me if you need a hand..Just remember, it's still their applet so give Intel proper credit.
