I finally succeeded!

When you select one or several countries from a map, as the European, it is necessary to add a basemap. I think there must be a problem with the basemap that I used at the beginning.

It only remains for me to find a European basemap only (or even better French) and it will be perfect.

A small question, is somebody has already managed to open these IMG file?
When I see this file: [Only registered and activated users can see links. ]
More precisely its structure ... and this name...

I think it should be possible to either create its own img file.
