You don't have to define an output format for GIF/PNG/JPEG formats
unless you want to change their default behavior.
So, just changing IMAGETYPE GIF to IMAGETYPE PNG24 will work.
See http://biometry.gis.umn.edu/tutorial/example1-5.html or maybe the
entire section 1 (mapfiles). Or download the materials from here:

David,
I think my biggest problem at this point in learning MapSever is not
knowing how things go together as the MapServer documentation is a bit
spotty and scattered. But you gave me the clue and by guessing I
eventually hit on defining an OUTPUTFORMAT object for gif images with
IMAGEMODE set to RGB instead of PC256. Now it looks good -- Thanks!
OUTPUTFORMAT
NAME gif
DRIVER "GD/GIF"
MIMETYPE "image/gif"
IMAGEMODE RGB
EXTENSION "gif"
END

Bill,
I am guessing that you either have not designated an imagetype in your
map file, or you are using 8 bit png or gif.
For maps with air photos, you will likely want to use jpeg or png24.
PNG24 looks very nice, but the output images can be pretty large and
therefore slower to serve up.
David.

Subject: [UMN_MAPSERVER-USERS] How to Improve WMS Image Quality?
After getting my last message swamped by an out-of-control
autoresponder, I thought I'd better try again. So here's my question
again:
I've linked DOQ images from the Microsoft TerraServer's WMS, but they
look terrible in my MapServer map. It looks like they are being rendered
in 8-bit grayscale. When I display these same images with a GetMap URL
in my browser they look fine. Could someone tell me what I need to do to
get these to look better in MapServer?
