The first thing that comes to mind is the extent. I may be off, but this is the first thing I'd check.
> # minx miny maxx maxy > EXTENT -180 -90 180 90 # World > Upper Left ( 168297.500, 761002.500) ( 72d 0'3.71"W, 6d52'31.02"N) > Lower Left ( 168297.500, 747032.500) ( 72d 0'0.88"W, 6d44'56.70"N) > Upper Right ( 182257.500, 761002.500) ( 71d52'29.42"W, 6d52'33.81"N) > Lower Right ( 182257.500, 747032.500) ( 71d52'26.72"W, 6d44'59.44"N) > Center ( 175277.500, 754017.500) ( 71d56'15.18"W, 6d48'45.26"N) At a size that small, compared to the rest of the map, I'd expect the image to be entirely white, with your TIFF represented by a single pixel. I'd try setting the map's extent to be zoomed in a little tighter, e.g. EXTENT -72 6.75 -71.9 6.9 -- HostGIS Cartographic development and hosting services 707-822-9355 http://www.HostGIS.com/ "Remember that no one cares if you can back up, only if you can restore." - AMANDA
