Hi, Have a look at gdalinfo reports about the slow image and about one of the fast ones. Check if there are considerable differences in image sizes in pixels. If images are about as big then look at the file formats and see if they are somehow different. -Jukka Rahkonen- _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
