<script src="http://code.jquery.com/jquery-1.6.4.js"></script>
<script>
    var slideIndex = 1;

脚本显示缩略图图像，最大值我们需要4个出现在大图像的底部。当我们点击下一个和上一个时，缩略图上的图像会改变悬停但不会滚动。

当我们点击prev＆amp; amp;时，我需要你的帮助让缩略图图像滚动下一个（箭头按钮）。

提前致谢

我建议你使用fancybox脚本。您可以在此处下载：http://fancybox.net/

它是高度可定制的，您可以使用网站上解释的javascript中的某些设置完全按照您的需要进行操作。
