Blank image being created in MS 4.6.0

[Mike Boos]

In this case, no it does not. gdalinfo reveals no coordinate system - 
this is the system our mapfile-generating script provides when no 
coordinate system is available. (I didn't develop it, just maintaining 
it, so I'm not sure why it chooses that one) The way our server is 
supposed to work is that if the image has coordinate system info to it, 
it will project and display it appropriately according to that 
information.  If there is no information, we still need to display the 
image, so it generates the extent data based on the image size. This 
particular image has no world file or any other georeferencing info 
associated with it.

The image is displayed on its own, so I could take out the projection 
information. However, this does not cause the image to appear.
