需要在Javascript调整中进行EBAY幻灯片演示

我一直在寻找适用于Ebay的幻灯片脚本,并找到http://xlo.co/blog/web-development/javascript-image-fade?quip_thread=blog-post-19&quip_parent=76这个似乎正常工作的脚本。我想在幻灯片中添加第三个图像,这就是事情开始向南的时候。以下是我从原始页面更改以添加第三个图像的代码。

我放在我插入的任何代码旁边。但是,它可以在第一张图像后停止工作。如果任何人都可以提供帮助,那将会有很大的帮助。

<div id="test">alpha</div>
<div id="slides" style="display: none;">
<div id="slide0" style="background-image: url('/ebay/images/image1.jpg'); width: 670px; height: 240px;">Content0</div>
<div id="slide1" style="background-image: url('/ebay/images/image1.jpg'); width: 670px; height: 240px;">Content1</div>
<!--ADDITION --><div id="slide2" style="background-image: url('/ebay/images/image1.jpg'); width: 670px; height: 240px;">Content2</div>
</div>

<div id="transition" style="width: 670px; height: 240px;">
<!--ADDITION --><div id="imageholder2" style="position: absolute;"></div>
<div id="imageholder1" style="position: absolute;"></div>
<div id="imageholder0" style="position: absolute;"></div>
<!--first last to avoid messing with z-indices-->
</div>
