[OSM-talk] Downloading map images (update to MapOf)

[OJ W]

I've updated the "MapOf" application, that lets you download map
images for abitary areas:

http://dev.openstreetmap.org/~ojw/GetMap/

So new features are:
* Paste the URL of a slippy-map permalink instead of supplying
lat/long/zoom in separate fields
* More map layers
* Fixes the blank tile bug (blank land/sea tiles used to be shown as a
gap in the image)
* Option of adding attribution and licensing text to an image
* Support for tileservers that output JPEGs (e.g. openaerialmap)


It also means that we get this file:

http://dev.openstreetmap.org/~ojw/GetMap/layers_source.php

i.e. a list of free tileservers.  Are there any layers we should
add/remove from that list?  Are the fields sufficient for other
peoples' uses?

(this file will be on SVN in due course, along with the rest of the code)
