JavaScript MouseOver

There are two steps to creating a JavaScript feature.
First is the script that goes in the HTML Header. This is the area for defining the variables and functions, and preloading images, if required.
Second is the generation of the JavaScript in the HTML Body. This generally calls on the functions previously defined.

This example uses two simple functions. One is called by the MouseOver event, and one by the MouseOff event.

Note that there is a hyperlink activated when the cursor is on the image.
