This is a mapserver template variable. Mapserv itself will set this,
along with other template variables. Read more here:

Your reference image is a GIF and must be converted to PNG format. You
can use the convert program: convert ref.gif ref.png

Mapserver needs to know the path of a directory for creating temp files.
This path is specified in the map file. You can read more about that
here:
http://mapserver.gis.umn.edu/doc40/mapfile-reference.html
See the Web objects IMAGEPATH variable.

This is a tutorial for mapserver 3.5 but it should give you an idea of
how the basic system works.
