Chris, 
 
Can you post the text of your map file?  The mapfile attachments didn't
come through.  
 
Are you defining the projection explicitly by setting all of the
parameters, or are you just using the EPSG code like this?  
 
  PROJECTION
    "init=epsg:26916"
  END
 
Have you used the GDAL tools to check out the image.  Try running
gdalinfo on it to see what gdal reports for the referencing information.

 
David.

	Hi.  I'm trying to take an image that already exists and display
it through mapserver.  It's a map from a college campus that I will
eventually superimpose over another layer.  No matter what I do, the
image won't display.  For projection, I'm Using UTM projection, WGS84
ellipsoid, NAD83 datum.  The campus is University of Illinois in
Champaign/Urbana.  Since I'm using UTM, I know that the zone is 16.
I've geocoded the top right and bottom left corners of the campus.  The
Easting of the bottom left corner is 393,898 Meters and the Northing is
4,438,945 Meters.  The Easting of the top right is 396,253 Meters and
the Northing is 4,441,379 Meters.  I don't know if I'm leaving any
parameters out in the Projection object in either the Map Object or the
one Layer Object I have.  Plus, I don't know if I'm declaring the Extent
wrong.  On top of that, someone suggested to me that I'd need a world
file to specify where the image is located on a globe.  I've set one up
and am also specifying the values according to UTM, thought I'm not
really sure what the 1st and 4th value really mean (yes - I've read many
variations of the same definition for setting up world files).  I'm
using Ubuntu Feisty Linux and php Mapscript.  I'm attaching the world
file, .map file, and .php file.  The .gif file is too big but can be
located at: http://www.parking.uiuc.edu/campus_map/.  Click on "Larger
Image" and download that .pdf.  I used Photoshop to convert it to a
.gif, .png, .jpg, and .tif also and tried all of those but to no avail.
As far as Mapserver info:
	
	MapServer version 4.10.0 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG
OUTPUT=WBMP OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE
SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER
SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=THREADS SUPPORTS=GEOS
INPUT=EPPL7 INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE
DEBUG=MSDEBUG
	
	I'm stuck, and don't know what else to do.  I've spent almost 2
weeks trying to get this to work as I've been learning about Mapserver,
Mapscript, and projections.  Any help to point me in the right direction
would awesome.  Also, if this isn't possible to do and I'm beating my
head against a wall, that would be helpful too.  My head hurts.  Thank
you in advance.
	
	 - Chris
