网站首页图片动态更换显示【Javascript】

以前写过一篇网站首页图片动态更换显示【Flash】，主要是介绍了一下网站首页常见的图片新闻更换程序。今天上网发现一个用Javascript脚本写的，效果也很是不错，来看一下：

跟Flash版的几乎一样，看一下代码吧，主要是JS：

<html>
2

<head>
3

.ImgChange1 { FONT-WEIGHT: bold; FONT-SIZE: 12px; WIDTH: 100%; LINE-HEIGHT: 20px; TEXT-ALIGN: center }
5

.LinkTD{ padding-top:10px;padding-right:20px;}
6

</style>
7

</head>

<div class="ImgChange1" id="focusPic1" style="display:block">
