楼上看清楚，天极那个不是用flash而是用js做的。

1.保存js代码：

2.拷贝以下代码到你的网页,并把图片和链接改为你自己的：

<div class="box-1">

<div class="box-1-l">

<div class="clear1"></div>

<div class="box100">

<div class="box1-l-left">

<SCRIPT language=javascript>

var widths=282

var heights=164

var counts=6

img1=new Image ()img1.src=''

img2=new Image ()img2.src=''

img3=new Image ()img3.src=''

img4=new Image ()img4.src=''

img5=new Image ()img5.src=''

img6=new Image ()img6.src=''

url1=new Image ()url1.src=''

url2=new Image ()url2.src=''

url3=new Image ()url3.src=''

url4=new Image ()url4.src=''

url5=new Image ()url5.src=''

url6=new Image ()url6.src=''

</SCRIPT>

<SCRIPT src="softindexfocuspic.js"></SCRIPT></div><!--注意此js和页面的路径关系问题-->

3.你所说的什么有阴影只是一张背景图片而已。
