请问如何才能让图片循环更新，现在这代码只是3张图片更新完了就结束了！
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
<script type="text/javascript">
var currentImgNumber=1;
var numberOfImages=3;
function window_onload()
{
setTimeout("switchImage()",3000);
}
function switchImage()
{
currentImgNumber++;
document.imgAdvert.src='AdvertImage'+currentImgNumber+'.jpg';
if(currentImgNumber<numberOfImages)
{
setTimeout("switchImage()",3000);
}
}
</script>
</head>
<body onload="window_onload()">
<img src="AdvertImage1.jpg" name="imgAdvert" />
</body>
小弟新手一个，请哪位大佬指点指点！

setTimeout（）只是定时执行一次，用setInterval();定时不断执行 -
元芳怎么了
var currentImgNumber=0; // 0~2var numberOfImages=3;function window_onload(){ setTimeout("switchImage()",3000);}function switchImage(){ document.imgAdvert.src='AdvertImage'+(currentImgNumber+1)+'.jpg'; currentImgNumber++; currentImgNumber %= numberOfImages; setTimeout("switchImage()",3000);}
