RE: SPAM-LOW: [mapguide-users] Raster files
To add another data point to this, I recently did something similar, but I chose a different approach. I used gdal to combine all the raster files into one big tiff, and then made an overlay pyramid for that TIFF as well. This way, there is no need for the configuration file or tile index. However, if your rasters are not neatly tiled and contiguous like mine were, then this approach will not work for you.
