Install the npm package.
Include the CSS file.

If you have a bundler that can handle CSS, you can import the CSS or include it with a <link> in the head of the document via the CDN
Include the following code in your JavaScript file (Example: main.js).

Replace YOUR_MAPTILER_API_KEY_HERE with your actual MapTiler API key.
The next is up to you. You can center your map wherever you desire (modifying the starting position) and set an appropriate zoom level (modifying the starting zoom) to match your users’ needs. Additionally, you can change the map’s look (by updating the source URL); choose from a range of visually appealing map styles from our extensive MapTiler standard maps, or create your own to truly differentiate your application.

Create a static image layer using the ImageStatic source. Set the image imageExtent Lng/Lat bounds. Here you can get the example image aerial_wgs84.png


 const layer = new ol.layer.Image({
 source: new ol.source.ImageStatic({
     url: './aerial_wgs84.png',
     projection: 'EPSG:4326',
     imageExtent: [4.639663696289062, 50.89935199434383, 4.642066955566406, 50.900867668253724],
 }),
 })
 map.addLayer(layer);
