Photo zoomer like this: is it possible in flash?

Hi everyone! This is a question for gurus. Look here:

This is made in Java. They want me to translate it in flash. The big problem for me is that (try to zoom and see), it always show an hi-res, arbitrary portion of the original image. It first loads a preview and than the hi-definition version, but without preloading all the hi-res image!!!

So, my question is not HOW to do it, not yet ;), but IF it is theoretically possible to do it in flash AS2 or AS3.

Anyone? :slight_smile:
