Hey Drewpolk,
first of all, thank you for the purchase!
At the moment the theme does not implement the Google Maps API (yet it is planned for the upcoming version update) – in the case of the header image in the “Contact” section of the demo website, I just used a screenshot of a map. I have a wide-screen monitor, so it was possible to take a wider screenshot; in the case of smaller screens one can simply take two screenshots from slightly different angles and then combine them into one wider image. For the styling, I’ve used Google Maps Colorizr, but I suspect there are also other tools available for this purpose, not least the wizard by Google itself :)
Sincerely,
Andrii / Satori Studio
