Changing Images with onMouseOver
The three images below are used as links. An onMouseOver event handler is used to
replace each image with a "highlighted" version as the mouse moves over it. The black image is returned
with the onMouseOut event handler.
NOTE: This works only with Netscape 3.0. This technique is impossible in MSIE 3.0 and Netscape 2.0.
