Hi,

Not directly related to your question, but I believe your command needs some
tuning.  You are giving -t_srs but you should give also -s_srs because jpg/jgw
pair does not tell the original projection. I guess also that your aim is to use
the warped image with Mapserver WMS. If that is the case I would recommend to
create a tiled tiff with -co TILED=YES option.
