It's a really awful photography, Brian looks like a fat penguin, Freddie looks like a shipwrecked person, Roger's hair looks like brushed with a chewing gum, and John poorly fits into the picture.
Anyway, it's obviously from a studio, not a real landscape (as you can see on the inner photos of the album, changing the landscape color, from the same session). Probably in Munich, where they were recording, on May 1980, just for the release of the single, and making the individual ones for the album interior.
Interesting question, Kacio. Hope my response being for help!
