I did a render with gdal2tiles and was able to get it working fine in Merkaator. Something about the tile number origin being opposite in JOSM. > Maptiler is essentially a graphical front-end to gdal2tiles. Xjjk's version > is the command line version modified.

I'll have to drop Xjik a line and see if I can get a copy of the modified command line file. It seems there WAS a version of gdal2tiles tat was optimized for multi-core, but the author seems to be charging for it. There is a pre-made gdal install package for OSX, so it was extremely easy to get up. Click and install. > You'll still be limited by your CPU :P On a single core my 1.9GB image took around 6 hours.

I'll probably want to get the parallelized version first though. THanks!
