Scrolling images horizontally

I am looking for some script in flash, which is able to do the following:

I have some images which i just want to scroll horizontally with equal spaces in a specified fps and without any jerking. Is any way ??

Because i tried to do the same by using the simple motion tween, they are moving but also jerking, not in a certain level of perfection. So, i thought it might work best with some scripts.

So, any suggestions or any ideas ???

I am still working on FLash 5 :expressionless:
