OnMouseOver JavaScript (map based)
Move your mouse over the image
The most common way to make a mouse over JavaScript, is to cut
the picture up into blocks, and when the mouse is over the block
it will change the block image. But when you got small image files, this
can be more trouble than gain. So I made this MouseOver using the hole
picture, and when the mouse gets in the right area it will change the
hole image.
