Having trouble displaying GeoTIFF raster data

[Chieko Maene]

Thank you for your kind reply, Mr. Alpert & Mr. McNierney, but I am 
still not be able to figure out what is wrong.. sorry.

Mr. Alpert, I am quite sure that I passed the layer="DOP04" just like 
any other layers (shapefiles, POSTGIS data).. The one thing that I am 
not sure is that I used "init=epsg:26971" projection but in fact all my 
data are in feet, not meter. It didn't affect my other shapefiles & 
POSTGIS data, but will it affect raster data..?

Mr. McNierney, my "DOP04.tif" file is huge, actually.. 357MB, dimensions 
w=25000 x h=15000 in pixel. Could it be a problem..?

# IL STATE PLANE NAD83 UNIT=FEET is my data's projection
# EPSG:26971 is IL STATE PLANE NAD83 UNIT=METER

  "init=epsg:26971"
END

Thank you so much. Chieko
