I have the same problem here and thinking about the following solution. use gdal_merge.py or gdalwarp to create one big picture having 3 bands use rgb2pct.py to create a big picture having one band. use gdal_translate to create a geotiff (using inner tiles and LZW compression). use gdaladdo to create the the overviews you need The result should be one geotiff file (Probably a bigtiff if the size is bigger than 4GB). Geoserver supports geotiff out of the box. Geoserver 2.2.x supports bigtiff, Geoserver 2.1.x supports it recently. http://jira.codehaus.org/browse/GEOT-3931 If you are on 2.1.x and you need bigtiff support, you have to test with a nightly build.
