GIF Raster Data Problem

[Daniel Morissette]

Akio,

This is the -dev list, which is reserved for discussion relating to the
development of the software.

Questions relating to the use of the software should be sent to the
mapserver-users list, where there are hundreds of users willing to share
their knowledge.

Hint: your problem is most likely that you are missing a world file for
your .GIF image. The raster howto in the mapserver docs page will tell
you all you need to know about rasters.
