角度谷歌地图:将图像放在信息窗口

我使用谷歌地图api angular(https://angular-ui.github.io/angular-google-maps/#/api/windows）来显示带有标记的地图。标记的点有几个段落和一张图片的标签。

段落内容显示正确，但图像显示不正确。它的url是正确的。可以添加图像吗？

某些代码：HTML

    <ui-gmap-google-map center='datos.mapa.center' options="datos.mapa.opciones" zoom='datos.mapa.zoom'>
        <ui-gmap-marker coords="datos.marker_club.coords" 
                        options="datos.marker_club.options" 
                        idkey="datos.marker_club.id"
                        click="markerClick" >
            <ui-gmap-window show="datos.marker_club.show"  
                closeClick="markerClose(marker)" >
                <div><img class="mapa_escudo" scr="{{datos.escudo}}" width="32" height="32" />{{datos.club}}<br />Sede {{datos.sede}}</div>
            </ui-gmap-windows>
        </ui-gmap-marker>
    </ui-gmap-google-map>

JS-

    $scope.datos.club               = 'Club';
    $scope.datos.sede               = 'Sede';
    $scope.datos.escudo             = 'http://www.server.com/image.png';

      uiGmapGoogleMapApi.then(function(maps) {
              $scope.datos.mapa           = { center: { latitude: latitud, longitude: longitud }, zoom: zoom };
              $scope.datos.mapa.opciones  = { scrollwheel: true };        
              var icon = "http://maps.google.com/mapfiles/ms/icons/orange-dot.png";
          $scope.datos.marker_club = {    id: 1,
                                          coords: { latitude: latitud, longitude: longitud},
                                          options:{ 
                                                  draggable: false, 
                                                  icon: new google.maps.MarkerImage(icon),
                                          },
              };      $scope.markerClick = function(marker, eventName, model) {
    $scope.datos.marker_club.show = !$scope.datos.marker_club.show;
};
$scope.markerClose = function(marker) {
   $scope.datos.marker.show = false;
};
