幻灯片专业-闪存加载,但图像不。为什么?

我安装了Slideshow pro,swfobject在这里: http://globalhealth-dev.oit.duke.edu/whos-involved/alumni

以下是html:

<object id="alumni" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="520" height="270">
<param name="movie" value="http://globalhealth-dev.oit.duke.edu/alumni-slideshow.swf" />
<!--[if !IE]>-->
<object type="application/x-shockwave-flash" data="http://globalhealth-dev.oit.duke.edu/alumni-slideshow.swf" width="520" height="270">

<!--<![endif]-->
<div>
    <h1>Alternative content</h1>
    <p><a href="http://www.adobe.com/go/getflashplayer"><img src="http://www.adobe.com/photos/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player" /></a></p>
</div>
<!--[if !IE]>-->
</object>
<!--<![endif]-->

</object>

以下是swfobject代码:

<script type="text/javascript">
swfobject.registerObject("slideshow", "9.0.0", "expressInstall.swf");
    swfobject.registerObject("alumni", "9.0.0", "expressInstall.swf");
</script>

这个图像.xml文件和库都在根目录中,xml文件代码为:

<?xml version="1.0" encoding="UTF-8"?>
  <gallery>
   <album title="Alumni" description="Duke Global Health Institute Alumni" lgPath="gallery/album1/lg/">
  <img src="kohler.jpg" />
  <img src="zimmerman.jpg" />
  <img src="griffin.jpg" />
   </album>
</gallery>

如果能帮我解决这个问题,我将不胜感激!谢谢。
