A data source containing an image. (See the [Style Specification](<https://maplibre.org/maplibre-style-spec/#sources-image>) for detailed documentation of options.)

## Example

```ts
// add to map
map.addSource('some id', {
   type: 'image',
   url: 'https://www.maplibre.org/images/foo.png',
   coordinates: [
       [-76.54, 39.18],
       [-76.52, 39.18],
       [-76.52, 39.17],
       [-76.54, 39.17]
   ]
});

// update coordinates
let mySource = map.getSource('some id');
mySource.setCoordinates([
    [-76.54335737228394, 39.18579907229748],
    [-76.52803659439087, 39.1838364847587],
    [-76.5295386314392, 39.17683392507606],
    [-76.54520273208618, 39.17876344106642]
]);

// update url and coordinates simultaneously
mySource.updateImage({
   url: 'https://www.maplibre.org/images/bar.png',
   coordinates: [
       [-76.54335737228394, 39.18579907229748],
       [-76.52803659439087, 39.1838364847587],
       [-76.5295386314392, 39.17683392507606],
       [-76.54520273208618, 39.17876344106642]
   ]
})

// update with an already-decoded image (no network request)
const bitmap = await createImageBitmap(myCanvas);
mySource.updateImage({image: bitmap});

// create an empty source (no url), then feed it entirely via updateImage
map.addSource('empty id', {
   type: 'image',
   coordinates: [
       [-76.54, 39.18],
       [-76.52, 39.18],
       [-76.52, 39.17],
       [-76.54, 39.17]
   ]
});
(map.getSource('empty id') as ImageSource).updateImage({image: bitmap});

map.removeSource('some id');  // remove
```
