Orthophoto/DSM, images shall contains pyramids to offer a better loading in Descartes/CCE/MS

There is no pyramid in the picture. Pyramids are lower resolution copies of the image (the equivalent of the caches that Raster Manager creates). it should contain an option that allows the user to create Geotiffs that contain the pyramids. In this case Raster Manager would not need to create caches on opening and it would be much faster.
