I really love Slideshow 2! JavaScript class for creating slideshows. It is super easy to use and customize. The only thing I wish it was based on jQuery instead of MooTools.

Well, I just found CrossSlide. I have not actually tested yet, but from the demo it has the basic functions of Slideshow 2! except the navigation bar. The better thing of course because it is based on jQuery, so I am happy to have this option. I am sure over time more feature will be added.

My full support for Tobia Conforto, the creator for this cool jQuery plugin.
