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...
#94 added Print this Map button
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.
semifinal changes; video link, small bugfix, #94
