Blank image being created in MS 4.6.0

[Brent Fraser]

Mike,

  You don't have a PROJECTION definition for your map (the target image to
be created by mapserver).  And your EXTENT coordinates look like pixel
values instead of world coordinates (e.g. meters or degrees).

  Try changing
EXTENT 0 0 576 432
  to
EXTENT 300000 5000000 700000 6000000
  or better yet, get the world extents of your input jpg file by using:
        gdalinfo  C:\inetpub\ftproot\input_images\AUG162454635.jpg


You might want to add

PROJECTION
  "init=epsg:32611"
END

after the EXTENT entry as well.
