[OSM-talk] Using images as a backdrop for editing OSM data

[Ævar Arnfjörð Bjarmason]

I have several free images which show some data I'd like to have on
OSM, e.g. administrative regions like this one:
http://commons.wikimedia.org/wiki/Image:S%C3%BDslur_%C3%A1_%C3%8Dslandi.png?uselang=is

What I'd like to do is import this image into some OSM editor and be
able to adjust its size and dimensions to fit the area I'm working on,
in this case a whole country.

I normally use JOSM but does any OSM editor have support for doing
this? Preferably something easier than having to write my own WMS.
