How to load different images as i zoom in and pan.

Helo, I'm creating a map in flash, with a jpg ordinance survey map as the background to show the roads etc. Can I split this huge image into smaller pieces and load them only when the user is viewing that area or near to it? And can i load different images as the user zooms in ?
thanks.

I know how to use XML , would that be the way to go?

Currently, I have set up an XML file to pull seperate swf files (the postcode areas) into a main swf file (the entire map). I am tryign to intergrate zoom and pan functions along with a minimap- its a huge task , and i'm rubbish at actionscript ! I'm slowly getting there by altering someone elses code to suit..
