I have 70Gb of raster data from drone photography that I need to serve via Openlayers.

The data is currently provided as georeferenced jpegs each is 175Mgb in size.

What is the best strategy to cut these into manageable tile sizes for serving via the web.

I have access to the gdal suite and was looking at the gdal2tile.py script. Can this be run on a set of tiles to produce a directory of georeferenced smaller tiles?
