Description
Allow to implement images rollovers by simply defining the images of a specific CSS class.
Then you only have to call the function "rollover_register()" and pass it the optional parameters:
- the CSS class you want to trigger. Default: "img.rollover".
- the pattern you want to add to the original image (e.g.: image.png and image.over.png). Default: ".over".
- the handler function for onMouseOver.
