Is it possible to save any of these maps as jpg or png images? There's a few that I'd like to use for other projects, so I was curious if this was even possible. This map was one I was particularly interested in:

Thanks!

There is no built-in mechanism that I know of. You could mail the map creator and ask them for the SVG file they used for the map. That'll probably be by far the most versatile file since you can resize it to any dimension or edit it, etc.

Plus it would give them the opportunity to consent to your use of their artwork.

EDIT: Wouldn't work here, as Issander is long since retired.

Only way I see is to make a Screenshot
