XML Image Rotator - so close - needs controls

I’ve found this xml driven banner rotator here on Kirupa from Mr. Daytripper.

It’s great (with preloader, xml controlled transitions, speed, urls) but I need to be able to add additional control with a 1 - 2 - 3 - 4 buttons that would jump to image 1, 2, 3 or 4 and maybe pause/play.

I’ve added the buttons but don’t have any idea how to control the arrays/variables.

I’m attempting to make it like a *standard *banner rotator like you might see on the homepage of Target.com, Bestbuy.com, but honestly the code is a beyond me.

If anyone would be willing to help by helping me figure out what code to put on the 1 - 2 - 3 - 4 buttons, I’d really appreciate it.

Thank you.
