Feature Request: Change image in source

[jordandalley]

Hi there,

I have a feature request to be able to change an image url in real time in a source.

For example, if I were to add an image source like the following..

map.addSource('radarimg',{
type: 'image',
url: 'https://someserver.com/image1.png',
coordinates: [
[0, 0],
[0, 0],
[0, 0],
[0, 0]
]
});
map.addLayer({
id: 'radarimg',
source: 'radarimg',
type: 'raster'
});

Now, say I have an array of images that I would like to change on the fly using a setTimeout, something like this:

map.getSource('radarimg').setUrl('https://someserver.com/image2.png');

I have tried setting each individual image as its own layer and source, and turning the layers on and off like in the example here: https://www.mapbox.com/mapbox-gl-js/example/animate-images/

However, in large volumes of images, this is highly inefficient.

If I've missed something here, I apologise. I am a bit of a noob.. :)
