The best way to add "Blue Marble" maps to SatPC32 is to download and install the latest version, 12.7. With a single mouse click you can switch between the old political map (showing country boundaries) and the new Physical Map (satellite composite image from NASA's earth observatory).

On the web page you can see screen captures of the Political and Physical maps, for comparison.

Be sure to REGISTER your downloaded copy of SatPC32 with AMSAT. All the money goes to support AMSAT programs.
