Transm.js allows you to add programmable image transitions to your web-pages. 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 along with filter or opacity, else it’ll degrade and your visitors won’t notice a thing.
