Maybe it would be a good idea to tell us something about the nature of 
the image you'll be displaying (though the fact that it needs a 
cross-hair or something is useful information, for a start).  For 
example, is it a photographic image?  A map?  A drawing?  Is it 
generated dynamically, or is it static?  Do you pan over it, or zoom it, 
or what?
