AW: [mapserver-users] Problems displaying tiffs and jpegs

[Nicole Bömeke]

I did not change the top of the demo makefile,
that means I used the following settings with no PROJECTION defined:

NAME DEMO
STATUS ON
SIZE 600 600
EXTENT 388107.634400379 5203120.88405952 500896.339019834 5310243.30613897
UNITS METERS
SHAPEPATH "data"
IMAGECOLOR 255 255 255

WEB
  HEADER demo_header.html
  TEMPLATE demo.html
  FOOTER demo_footer.html
  MINSCALE 1000
  MAXSCALE 1550000
  IMAGEPATH "set in demo_init.html"
  IMAGEURL "set in demo_init.html"
END

Nicole,

The .wld files are in some kind of projection in METERS. What does the
top of your mapfile look like? Have you specified a PROJECTION .. END?
What are your EXTENTS? What are your UNITS?

I think maybe these do not match your images. Which would account for
your images not showing up.
