[Mapserver-users] jpeg output

[Christina Biakowski CCGIS]

Hello,
I have installed MapServer using the by dmsolutions provided
Windows-binaries version mapserver-3.6.4-win32-php4.3.0-libwww:
MapServer version 3.6.4 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
SUPPORTS=PROJ SUPPORTS=TTF SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT
INPUT=EPPL7 INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE

Though JPEG is supported I can't render jpg-images as output. Using the
other formats everything works fine.
Do I have to install an additional library to render jpgs?

Thanks in advance!

Christina
