Yes, I'm familiar with many of these sources actually. The problem is TG2 can't load them, at least not on my machine. It choked on a 21600x10800 .jpg, so I'm not going to be trying anything above that. Perhaps if TG2 gains support for dynamic reading and mip-mapping of tiled data sets this would be practical, but for now without a 64 bit version I think not, unfortunately. The point of the project is to do the best we can *at present*, and a big part of that is finding the highest resolution that will render consistently.
