mapper.js 2.3 allows you to add automatic area highlighting to image maps on your webpages (inc. export to SVG).

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.

transm.js 1.0 allows you to add programmable image transitions to your webpages. It uses unobtrusive javascript to keep your code clean.

It works in all the major browsers – Mozilla Firefox 1.5+, Opera 9+, Safari 2+, Chrome 3+ and IE 6+. Works also on older browsers supporting JS 1.5 and images and filter or opacity, else it'll degrade and your visitors won't notice a thing.
