This script creates an effect to scroll images around the stage. In this way you can have large images and still give the user the possibility of seeing the entire image – you can also use this effect when zooming in on images.

It is well documented, and it is easy to customize speed and size of the button etc. 

Images loaded dynamically cannot be larger than 2880×2880 px – that’s the limit for Flash. To use larger images you must import them into your flash file.
