Move your mouse over an image to see the description. Works on IE 4+,
Netscape 3+ and newer, Firefox, Mozilla, and Opera.
This example does several tricks. It preloads images for a faster
button-switching experience. It switches images to make the buttons look
pressed. It switches images to put an image-based description between the
buttons. It changes the text in the box for a text-based description. It
also writes a description to the window's statusbar.
