Dear Daniel, I would need some more info in order to get back to you with something helpful.
Anyway, what I can give you is that: -1- I would go ahead with converting to geotiff and using the geotiff store (use gdal_translate) -2- I would add overviews using the average interpolation algorithm which should give you enough quality. It is always better to prepare overviews in advance using the proper interpolation method. Regards, Simone. ------------------------------------------------------- Ing.
