jvectormap markers label image

does anyone know how to add two different images to two different marker's labels?

$('#map').vectorMap({
    markerStyle: {
      initial: {
        fill: '#F8E23B',
        stroke: '#383f47'
      }
    },
    backgroundColor: '#383f47',
    markers: [
      {latLng: [46.90, 8.45], name: "Italy"},
      {latLng: [26.02, 50.55], name: 'Bahrain'},
    ],
    onMarkerLabelShow: function(event, label, code) {
     label.html("<img src=\"img/logo.png\"><br>"+ label.html());                
    }
});

this displays the same image on both markers
