Improved Map images in Map MFD ...

[llarian]

Normally, the standard Map MFD is just fine for me. However, I started experimenting and decided to try to use upgraded imagery in the Map MFD. I downloaded and installed the Hi-res Map images (for Mars in this case). When I go back to check the Map MFD in the program, there is no change. Just the usual green line MFD. Can't remember what I missed. Can anyone suggest how I can change that map image?

I'm using the Orbiter 2016 (latest build from the GitHub site).
