Georeferenced JPEG

[Richard A. Milewski]

How do I tell MapServer to use the georeferencing information in a JPEG?

I can see the data with gdalinfo, and if I copy the Origin and Pixel Size
parameters into a .wld file everything works fine.

mapserv -v says INPUT=GDAL

I've found the OUTPUTFORMAT object, but there doesn't seem to be an
INPUTFORMAT object.

...I get the feeling I'm missing something obvious.
