Hello,

My quick thoughts:

- remove all projection objects
- use the commandline gdalinfo utility to get the extents of your image 
(Lower Left and Upper Right coordinates) and use those values in the 
EXTENT parameter
- test your mapfile with the shp2img utility 
(http://www.mapserver.org/utilities/shp2img.html)
