Horizontal scroller how to

Hi

How would you guys go about creating an horizontally scrolling panel of thumbnail images?

I want a panel that scrolls for ever in both directions and it also needs to be controlled via two arrow buttons not a mouse over type scroller. I would also like to animate with Tweens in action script to get a nice smooth scroll.

I know some as3 but I can’t work out how to make the scroller repeatedly scroll in both directions.

Could anyone help get me started on the right track please?

No oop please Im a timeline based code man at the moment.

Thanks

Ricky
