鼠标放到图片上，图片慢慢变清淅

Step1：

首先请在<head></head>之间粘贴如下代码：
<SCRIPT language=JavaScript>
nereidFadeObjects = new Object();
nereidFadeTimers = new Object();
function nereidFade(object, destOp, rate, delta){
if (!document.all)
return
    if (object != "[object]"){  //do this so I can take a string too
        setTimeout("nereidFade("+object+","+destOp+","+rate+","+delta+")",0);
        return;
    }
    clearTimeout(nereidFadeTimers[object.sourceIndex]);
    diff = destOp-object.filters.alpha.opacity;
    direction = 1;
    if (object.filters.alpha.opacity > destOp){
        direction = -1;
    }
    delta=Math.min(direction*diff,delta);
    object.filters.alpha.opacity+=direction*delta;
    if (object.filters.alpha.opacity != destOp){
        nereidFadeObjects[object.sourceIndex]=object;
        nereidFadeTimers[object.sourceIndex]=setTimeout("nereidFade(nereidFadeObjects["+object.sourceIndex+"],"+destOp+","+rate+","+delta+")",rate);
    }
}
</SCRIPT>

Step2:

然后在需要加入特效的图片的<Img>标签里加入如下代码；
onMouseOver=nereidFade(this,100,10,3) style="FILTER: alpha(opacity=10)" onMouseOut=nereidFade(this,10,10,3)
