Image in Google Maps infoWindow

I’m trying to make a marker with an infoWindow looking something like this, but I can’t really figure out how to add an image:

Do anyone of you have any idea how this should be done?

Currently, my markers and infoWindow are set like this:

addMarker(map, latitude, longitude, title, artist, id) {
    // create LatLng object
    let ionic: LatLng = new LatLng(latitude, longitude);

    // create new marker
    let markerOptions: MarkerOptions = {
      position: ionic,
      title: title,
      snippet: "Av " + artist,
      icon: {'url': 'www/assets/images/landemerke.png', 'size': {
	       width: 37,
	       height: 49
    this.marker = map.addMarker(markerOptions)
      .then((marker: Marker) => {
            (data) => {

The solution was to set up a canvas inside the infowindow:
