Move the mouse pointer away from the link. As soon as the mouse pointer is no longer
on the link, the mouseout event occurs and the onmouseout event handler is triggered.
This displays the alert box, as shown in Figure 14.12.
You can combine event handlers in one hypertext link. This is the essence of the image

technique is beyond the scope of this chapter, but perhaps this demonstration sheds
some light on how image swapping is accomplished.
