OK, we could try to prompt people to enter a title, and we could also by default display the longitude/latitude of the map. But otherwise, this seems to be working!

OH, wait - this is related to another issue. The JPEG is unprojected, meaning latitude and longitude are 1:1, which isn't really how the earth is shaped. This makes the maps look "smushed" especially far from the equator. We could set up GDAL to reproject jpgs in spherical mercator...

still not at 100%, need to make jpg (spherical mercator) output with a white background instead of black. Harder than it looks...

See some variations on this here: http://publiclaboratory.org/wiki/gdal-commands

but still haven't figured out how to get a spherical mercator JPG with a white background using only a GDAL or ImageMagick command. Ug.
