I want to add a png icon to a mapbox map from any publicly available online source.
I'm trying to use this example here from mapbox.com, which uses a png from wikimedia:
https://docs.mapbox.com/mapbox-gl-js/example/add-image/
This is the png they use:
I can swap it out from anything at Wikimedia, but not anything else. For example, swap the link out with this one, and it doesn't appear:
https://www.thenittygritty.org/coronavirus/circle1.png
What am I missing here??
