gdalinfo is telling you that the upper left corner is at
(-521, -371) but you've put (-521, 371) in your tfw file. Given your
coordinates that shouldn't matter much, however. Could you post your MAP
file so we can see the EXTENT and other settings you're using? That's a
somewhat unusual-looking raster image, but it should be OK if set up
properly.

Hi
Yeha thats fine and i ahve used the values from my gdainfo to
.tfw file but it all the same. But if i use the mapserver demo
application's .tif file(Which is anyway not similar to projection
that i am using) it is coming in the browser along with other
layer. So i assume my values in the .tfw files are wrong. I have

And My test.tfw file for test.tif is something like this-->
1042.0
0.0
0.0
742.0
-521
371
I have not used any projection statement in my
0.0
0.0
742.0
-521
371
I have not used any projection statement in my
mapfile/phpmapscript.
Plz. guide me.
