Sorry Alans,

I forgot an import step:

After verifying SRP support with 'gdalinfo --formats', next step is to 
see if GDAL can read your exact file, by using gdalinfo again:

   gdalinfo myfile.img

You should see some info returned such as Size, Pixel Size, 
Coordinates...etc.

Then you can focus on your mapfile layer.
