Angular - 动态设置html img的宽度和高度

Question

我想在angularJS应用中使用jQuery BeforeAndAfter插件。但我有几个不同尺寸的图像。我试图动态设置宽度和高度，但它不起作用。像这样：

        <div id="container">
            <img id="imgMY" ng-src="{{photo.source}}" alt="photo" width="{{photo.width}}" height="{{photo.height}}"/>
            <img id="imgM2" ng-src="{{photo.source}}" alt="photo" width="{{photo.width}}" height="{{photo.height}}"/>
        </div>
    ...
<script type="text/javascript">
    $(function(){
        $('#container').beforeAfter({
        animateIntro : true,
            introDelay : 1000,
            introDuration : 500,
            showFullLinks : false,
            dividerColor  : '#1481E3'
    });
    });
</script>

仅当我将这些属性硬编码时才有效。我怎么能搞清楚？

使用ng-style指令。

示例： <img ... ng-style="{ width : photo.width, height : photo.height }" />

angular.module('test', [])
  .controller('TestController', ['$scope', '$document', '$timeout',
    function($scope, $document, $timeout) {
      $scope.photo = {
        link: 'https://pbs.twimg.com/profile_images/2149314222/square.png',
        link2 : 'http://cdn-prod.portlandwebworks.com/sites/default/files/angular-3.jpg',
        style: {
          width: '300px',
          height: '200px'
        }
      };
      
      $timeout(function() {
        $('#container').beforeAfter({
          animateIntro: true,
          introDelay: 1000,
          introDuration: 500,
          showFullLinks: false,
          dividerColor: '#1481E3'
        });
      });     
    }
  ]);

  </div>
</div>

仅供参考（已更新）：无需预加载图片即可正常运行，但插件会从这些图片中捕获宽度和高度。
