The Stede Broec problem has been solved. The template now looks for an image called "LocatieStede_Broec.png", with an underscore. This means you have to rename the map before you upload it to the English wikipedia. I couldn't find any other way to get it working, unfortunately.
 It is not possible to calculate the density automatically, I'm afraid.  17:04, 30 Aug 2004 (UTC)
