I need script to load pictures from file

Hi

I am trying to recreate a banner I did awhile ago for this webpage http://selectivedesigns.com/  it needs to be the same thing except I need to be able to change the photos in the banner by just changing pictures in a folder.

Is there a way to do this and still keep all of the fading properties and loop?

Thanks (still trying to figure out this script stuff xD)
