Make a festival map

I guess it might be interesting to extend the OpenStreepMap app uploader with a menu that allows you to upload an image and then match 2 points on it against a map view (eg click on 2 buildings on the image you uploaded and match those against the same buildings on the map).

When that was done, the image could be uploaded and the relevant metadata file created to make the map appear automatically alongside all the other ones on the Bangle.
