、淡入淡出：（支持多个图像，只要加上 class="fade"　就行了！）<style>
img.fade{
filter: alpha(opacity=30);
border: 0px;
windy: expression(onmouseover=function(){fade(this,true)},onmouseout=function(){fade(this,false)})
}
</style>
<script language="JavaScript1.2">

var timer=null;
var last_img = null;
var org_opacity=30;

var ext_time=100;function fade(img,mode){
