  I think he is confusing photon maps with lightmaps (common rendering
technique for fast precalculated lighting).

  Theoretically you can certainly create lightmaps *from* photon maps, but
unless the renderer you are using supports lightmaps they will not be of
any help (POV-Ray does not support them because it would require UV-mapping
for all objects; lightmaps are most useful in scanline rendering).
