For the record, this is the image that the example try to load: "http://eoimages.gsfc.nasa.gov/ve//2433/land_shallow_topo_2048.jpg" (https://github.com/enthought/chaco/blob/main/examples/demo/world_map.py#L37)

We could replace it with https://neo.gsfc.nasa.gov/servlet/RenderData?si=1845687&cs=rgb&format=JPEG&width=720&height=360

After replacing with this link, a 403 error is caused.

How about this world map: https://upload.wikimedia.org/wikipedia/commons/9/91/Winkel_triple_projection_SW.jpg

Yeah, if you use requests it will work, but here is what I get if placing it in the world_map demo:
