Post your EXTENT and PROJECTION information for you map file. Most of the time when something just doesn't show up it's and EXTENT/PROJECTION problem or you didn't pass layers=DOP04 in the URL

The strange thing is, I don't get any error message when rendering the output PNG image - and still there is no aerial photo. My map and the GeoTiff are in the same coordinate system (init=epsg:26971) so I thought simply adding a layer to the .map file would work, but it didn't. I think I am missing something very simple but don't know what. Will anybody please advise me? Any input would be appreciated. My test site is: http://cmaene.lib.uic.edu/apress/campusmap11.php I am using PHP/mapscript 4.6 (MapServer for Windows, MS4W, pre-compiled .exe version) on Microsoft-IIS/5.1, and here is the version string from MapServer & MapScript: MapServer version 4.6.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=PDF OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE DEBUG=MSDEBUG PHP MapScript Version ($Revision: 1.235 $ $Date: 2005/06/14 16:03:35 $) The layer info: ##################################### # the output IMAGETYPE is PNG # the input GeoTIFF is in the same SHAPEPATH LAYER NAME "DOP04" TYPE RASTER STATUS on DATA "DOP4.tif" PROJECTION "init=epsg:26971" END END ##################################### I tried: - switchig layer status to "on" or "default" - adding a world file (.tfw) to the GeoTiff 0.550000000000000040 0.0 0.0 -0.550000000000000040 1159375.2749999999 1900374.7250000003 - adding "PROCESSING" and/or "PROJECTION" classes to the layer in the map file to make sure that the GeoTIFF file is read via GDAL. - converting the GeoTiff to JPEG using Photoshop and then add a world file (.jgw) - again, the airphoto didn't show-up, but no error message. - converting the GeoTiff to PNG using tiff2png and PNG2, but the conversion attempts failed (lack of memory?? original GeoTIFF is 350 MB, or the header information wasn't read properly?)
