Render a static continent image

I'd like to be able to grab http://ps2maps.com/briggs/indar.jpg as a map of the current territorial control, perhaps updated every couple of minutes. This would let me put the maps in things like desktop widgets that can't display a full webpage (e.g. Rainmeter). 

If there was support for ?size=small (300px), ?size=large (900px) etc, that would be appreciated too.
