# Add a raster image to a map layer
This example adds a radar weather image over a dark vector style.
To add the raster overlay, the example adds an [`image` source](https://docs.mapbox.com/style-spec/reference/sources/#image), and a [`raster` layer](https://docs.mapbox.com/style-spec/reference/layers/#raster) to the map.
> Example code:
**JavaScript**
```html

```
**React**
```jsx
import React, { useEffect, useRef } from 'react';

const MapboxExample = () => {
const mapContainerRef = useRef();
const mapRef = useRef();
useEffect(() => {
mapRef.current = new mapboxgl.Map({
