Check out WOW Slider http://wowslider.com/

Or Visual Slideshow www.visualslideshow.com

Both of these need a bit of tweaking to add to your website. Basically, you need to save the slide show or slider to a folder on your desktop. Create a placeholder the size of the height and width of the slide show or slider, then copy the Head material from the index file the software creates, and paste it into the Head area of the placeholder object. And you do the same with the body portion created.

When you publish the site the two folders created, Data and Engine need to be in the root directory.
