It seems that i can use MapServers Web Coverage Services (WCS) to generate an
image using the following in my mapfile:

OUTPUTFORMAT
    NAME GTiff
    DRIVER "GDAL/GTiff"
    MIMETYPE "image/tiff"
    IMAGEMODE "RGB"
    #IMAGEMODE "PC256"
    EXTENSION "tif"
END

But i am still not getting the full resolution of the images that i am
requesting.  Also i am still unsure how to download this image from the command
line, cant i use something like curl or sftp?  When i try to use curl i get the
following:

-- start output --

[root at neuron ~]# curl -O

-- end output --

Then nothing seems to happen. Any help with this would be great, thanks?
