Script modification for the thumbnails tutorial

I am trying to modify the “Adding Thumbnails” tutorial found here:

I would like to have the bottom thumbnail scroller start to scroll automatically upon page load. The two areas within the scroll area that currently control the moving of the scroll area would not be needed. Each thumb nail would also need to be clickable and point to their full size images. Currently, when the user causes the scroll to happen, it moves untill their are no items left in the array. I would like for the automatic scrolling to continually scroll, looping back to the beginning of the array when completed, over and over again.
