Smooth scrolling of large images - How to?

Hi,

I’ve created a very simple movie which you can see here http://www.airsauce.com/clients/bluesky/
but the scrolling of the images is very jerky. I’m aware that the way to achieve smoother motion is via actionscript but haven’t got a clue where to start.

The source file which includes 3 images is here

Any pointers would be very much appreciated :slight_smile:

Cheers, Danx
