使用json功能作为img scr中的变量

Question

我是javascript和网络地图的新手。我正在尝试创建一个显示城市周围壁画的地图。单击该点时，我希望弹出地图图像。这是我到目前为止所做的：

var address = feature.properties.address || 'Unnamed address';
var artist = feature.properties.artist || '(Unknown)';
var year = feature.properties.Year|| '(Unknown)';
var photo = feature.properties.image|| '<P>Photo not available</P>';
var titleHtml = '<p style="font-size:18px"><b>' + address + artist +'</b></p>';


document.getElementById('summaryLabel').innerHTML = titleHtml;
document.getElementById('muralImage').innerHTML = '<img scr='+ photo + '/>'

L.DomEvent.stopPropagation(e); // stop click event from being propagated further
          }
        });
      }
      map.addEventListener('click', function(e) {
        if (selection) {
          if (selectedLayer === muralsLayer)    selection.setIcon(iconByPassday(selectedFeature));

          selection = null;

          document.getElementById('summaryLabel').innerHTML = '<p>Click a mural on the map to get more information.</p>';
          document.getElementById('muralImage').innerHTML = ''
        }
      });

    }

对我来说很明显，以下是错误的，但我不知道如何解决它。

document.getElementById('muralImage').innerHTML = '<img scr='+ photo + '/>'
