Funny units for jpeg images

[John Hockaday]

Hi,

I am trying to get a jpeg to load as a background image with vector
data on top of it.  Both are in geographical coodinates however, when I
load one on top of the other they seem to be in different projections.

The world file for the jpeg looks like this:

------------------------
            0.000450
0
0
           -0.000450
150.000914
-33.998391
------------------------


The image is supposed to be from TL(150, -34) to BR(151.5, -35).  That
is 1.5 degrees by 1 degree with the top left corner at 150 degrees long
and -34 degrees lat.

Am I missing out on specifying a decimal degrees unit for my layers in
the map file?  The map file is attached.

I would be greatfull for any information if someone else has used
georeferenced jpegs and vector shapefiles in a geographic coordinate
system.

Thanks in advance.
