Newbie questions...

I knew that map_earth_day and map_earth_night are for the 2D geoscape so I didn't bother with them for this test, I used the GIMP'ed image to replace all four map_earth_season* images (as I didn't have four different seasons for it)

I managed to do that, it was easier than I thought. Now I just need to figure how to make the night lights work, but I will think about that later unless some kind soul helps me in the meantime. A thousand thanks for your help.

City lights go into the alpha channel of texture; how do you put them there depends on the gfx editor you use. And most of them provide only little support for editing the alpha channel
