I chose 'source' and

... 'target' because the source map can be georeferenced as is
probably the case in your example and you want to improve
georeferencing of the source map, i.e. you want to georectify some
images. Therefore the terms 'un-georeferenced' and 'georeferenced' are
IMHO a bit misleading.

Yes.

Yes, one of the images you want to georectify. In the new
Georectifier, the selection is restricted to the images in the chosen
group to avoid confusion, and the fields are labelled source and
target where appropriate. Also note that you can change the source
image to be displayed through the settings dialog in the new
Georectifier.

Yes.
