Automatically highlight image maps with mapper

mapper.js 1.0 allows you to add automatic area highlighting to image maps on your webpages. It works in all the major browsers - Mozilla Firefox 1.5+, Opera 9+, Safari and IE6+. On older browsers, it can use "jsgraphics" from Walter Zorn (if installed), else it'll degrade and your visitors won't notice a thing.

The effect is very cool and can be useful in image maps with many hotspots, like country or state maps.
