If you have some way of associating a coordinate system
with an image, then that coordinate system is, generally,
independent of the size of the image on the display.
I use an image object for exactly this reason. I can display
the image in resizeable graphics windows and *still*
navigate the image in its associated coordinate space.

Cheers,

David
