In the Map module, there should be a method to return a static image of the map for the specified coordinates. Google Maps API has the capability (Static API) and it seems the Apple Mapkit might also have the feature now. This request is fairly urgent and would be easier to implement, I hope.
Just want to point out that the "toImage()" method isn't good enough. I'm trying to use it, and although it works fine for a previously loaded map, it doesn't work at all if I only have the coordinates in the code and want to get the image in the background without having to load the map view itself (which takes time).
