Hello,
I modified a map using the editor, and then saved it as a map image.

But I don't know how to use it in a new game. It doesn't appear as a scenario, and there doesn't seem to be an option to us it as a map when you start a game.

You should save it from the editor as a scenario (Edit -> Save Scenario). Map Images are completely different thing (picture of the game situation).
