I've used the image example and set the projection to epsg:4326 in the 
options but if I change the bounds to the lat lon  values, the image 
disappears and the x,y coordinates on the map control do not show the 
lat lon values (should it ? or does the control just show screen 
coordinates ?).  Does anyone have a sample code of a single projected 
image ?
