What does "gdalinfo image.jpg" say? If you open it in OpenEV or QGIS,
or GIMP - is it colour or greyscale? Maybe your input jpegs are
greyscale simply?

A note. In your:

> r.in.gdalinput=image.jpg target=image.jgw

The "target=image.jgw" seems wrong. "target" is for GCP's, while
the .jgw files are simply world files for corresponding .jpg
(like .tfw for .tif).
