下面代码是要定时改变图片，但是不知道哪错了，是思路错了还是代码写错了？？出不来效果！
<html>
<head>
<title>多幅图片切换特效</title>
<script language="javascript">
var count=1;
function changeImg(){
var allPics=document.getElementsByName("pic");
for(var i=0;i<allPics.length;i++){
if(allPics[i].style.zindex==count){
allPics[i].style.display="block";
}else{
allPics[i].style.display="none";
}
}
count++;
if(count>4){ count=1; }
setTimeout("changeImg()",2000)
}
</script>
</head>
<body onload="changeImg()">
<div name="pic" style="position:absolute;width:800px;height:600px;left:200px;top:10px;z-index=1">
