Kleine Verbesserung zu meinen Code. Tausche meinen genannten Code, gegen diesen aus.

Code:

    var iconBase = 'images/pinimgs/';
    var myLatLng = {lat: 51.47987, lng: 6.780479};
    var contentStringDuisburg = '1.Fototreff Duisburg';
    var infowindow1 = new google.maps.InfoWindow({
        content: contentStringDuisburg
      });
    var marker1 = new google.maps.Marker({
        position: myLatLng,
        map: map,
        icon: iconBase + 'pin_gelb.png',
        title: '1.Fototreff Duisburg'
      });
    marker1.addListener('click', function() {
        infowindow1.open(map, marker1);
      });


    var myLatLng2 = {lat: 54.18034, lng: 7.891165};
    var contentStringHelgoland = '1. Fotoreise Helgoland';
    var infowindow2 = new google.maps.InfoWindow({
        content: contentStringHelgoland
      });
    var marker2 = new google.maps.Marker({
        position: myLatLng2,
        map: map,
        icon: iconBase + 'pin_grün.png',
        title: '1. Fotoreise Helgoland'
      });
    marker2.addListener('click', function() {
        infowindow2.open(map, marker2);
      });
