使用jQuery插件AD Gallery制作类似QQ相册功能

Question

实现的效果如：http://www.biuuu.com/p1244.html在 火狐狸运行 没错  在IE7 里就提示js 运行错误
 错误图如下：
     <script type="text/javascript" language="javascript">  $(function() {
    var galleries = $('.ad-gallery').adGallery(); // 运行到这句提示Microsoft JScript runtime error: 
                                                        Object doesn't support this property or method
    $('#switch-effect').change(
      function() {
        galleries[0].settings.effect = $(this).val();
        return false;
      }
    );
    $('#toggle-slideshow').click(
      function() {
        galleries[0].slideshow.toggle();
        return false;
      }
    );
  });
  </script>前台代码：
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
     <script type="text/javascript" language="javascript">  $(function() {
    var galleries = $('.ad-gallery').adGallery();
    $('#switch-effect').change(
      function() {
        galleries[0].settings.effect = $(this).val();
        return false;
      }
    );
    $('#toggle-slideshow').click(
      function() {
        galleries[0].slideshow.toggle();
        return false;
      }
    );
  });
  </script>
<div id="container">

      desc.animate({bottom: 0}, this.settings.animation_speed * 2);
