Chris, 
 
I see two parts to this:  
 
1.  To get your map file properly set up
 
2.  To confirm that your image is properly georeferenced.  
 
 
For the map file: 
 
Have you looked at the Raster Data HowTo?  
http://mapserver.gis.umn.edu/docs/howto/raster_data  This should give you some 
simple examples.
 
You shouldn't actually need projection blocks unless you are combining data 
from different projections or serving the data up as a WMS.  If you do need to 
use projections, and your data is in UTM Zone 16, using the epsg definition 
that I
sent in the last email will make it easier.
 
Get rid of the EXTENT line in your LAYER, I don't believe that this property 
exists.
 
Set your LAYER STATUS to DEFAULT.  
 
Get rid of the CLASS block in your LAYER.
 
 
For the image, run gdalinfo on it and see if the georeferencing information is 
correct.  You can get gdalinfo at http://www.gdal.org/
 
David.

        No, I'm setting all the parameters (well, as many as I can and 
understand).  I tried to follow the Proj.4 .pdf manual and I was kinda confused 
what lat_1, lon_1 and lat_2, lon_2 were supposed to be or if I even needed them.
        
        Here is my map file:

        I have that reference section in there although I really don't know the 
point behind it.  It didn't change a thing, so I commented it out.  Thanks so 
much David for your help!
