I've wanted to know where to get the script or how to make one for a long time and thought I'd finally integrate one into my site but I have no idea how to go about making one. I am talking about the Image news scripts on websites such as

http://www.wwe.com
http://www.tv.com
http://www.abc.com

As you can see, WWE uses flash for its image news script but the other two seem to be using HTML or Javascript.

Any Help on this? Difficulty, how to go about doing it, anything at all
