I found this simple yet powerful html content rotator and using in few of my projects. I think its worth sharing with the community. The library named
jShowOff: a jQuery Content Rotator
You can download the script from this location. It requires two file only, on css which you can copy to your own css file and the other one is of course the java script , there are two distribution for this library, I strongly suggest that you should use the min version.
