Nuno,

1. Are you able to see the image when you run a regular MapServer CGI
request (i.e.
http://iceds.ge.ucl.ac.uk/cgi-bin/wcs?map=/ge/data/iceds/alpha/umms/wcs_land3.map&layer=LC5&mode=map)?

2. Is your image 16- or 8-bit?  If 8-bit, perhaps you should replace
IMAGEMODE INT16 with IMAGEMODE PC256 in OUTPUTFORMAT (also replace the
NAME accordingly).

3. What Frank said in another post.

Cheers!
Perry
