Syntax
The extension allows users to embed a slippy map using the following syntax in their wiki code:



Older version (running on the above sites) took a syntax like this:

lat=51.485|lon=-0.15|z=11|w=300|h=200|format=jpeg

Users can discover suitable latitude logitude and zoom values by doing the following:
 * Edit the page
 * Use the slippymap syntax with any old values e.g. paste in the above example
 * Doing a preview
 * zoom/pan the right position,
 * Use the 'Get wikicode' button
 * Copy and paste the resulting wiki code into the editing box
 * Save the page
