<div id=demo style=overflow:hidden;height:139;width:232;background:#f4f4f4;color:#ffffff><div id=demo1><img src="http://www.vevb.com/uploads/allimg/131226/11140042X_0.jpg"><img src="http://www.vevb.com/uploads/allimg/131226/1113592D6_1.jpg"><img src="http://www.vevb.com/uploads/allimg/131226/1113592D6_0.jpg"><img src="http://www.vevb.com/uploads/allimg/131226/11135AM1_1.jpg"><img src="http://www.vevb.com/uploads/allimg/131226/11135AM1_0.jpg"></div>
<div id=demo2></div>
</div>
<script>
var speed=50
demo2.innerHTML=demo1.innerHTML
function Marquee(){
if(demo2.offsetTop-demo.scrollTop<=0)
demo.scrollTop-=demo1.offsetHeight
else{
demo.scrollTop++
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
