This works great but is there an easy way to change it so the screenshot is on the 'satellite' view instead of the map?

Hi @acrete, I have added a new parameter for the class.

So you can simply do:
gmd = GoogleMapDownloader(51.5171, 0.1062, 13, GoogleMapsLayers.SATELLITE)

Or the layer you want!

As a way of thank you for your help guys I want to share this version that works perfectly fine. Enjoy!

Is there a way to get this to collect all the images at a given zoom level for an entire area?

Why does it always show for me - "Could not generate the image - try adjusting the zoom level and checking your coordinates"?

Hi there. @jackhirsh @Anjali1808
I've made an edited gist to download the image with the center of the given lat and long.
And also, the way of sending download request has changed. So images can be downloaded at any zoom and any size without a single problem in 2022.

Have fun :)
