图片重叠带阴影

请用鼠标放上去看看效果

脚本说明:
把如下代码加入<body>区域中
<script>
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>
