raster maps and mapserver

[Matthew Perry]

Alexia,

  Can you show us the URL of the image request? Most likely you are
requesting a map with different extents than your GRASS raster. In
GRASS, try r.info rastername and see if the extents line up with the
extents in your mapfile and/or the requested image URL.
