图片向左不间断滚动
这段JS向上不间断滚动是正常的，但是我改成向左滚动就不行，不知道该怎么改：
<!--向上滚动代码开始-->
<DIV id=rolllink style= "OVERFLOW: hidden; WIDTH: 162px; HEIGHT: 120px ">
<DIV id=rolllink1 style= "WIDTH: 122px; HEIGHT: 560px ">
<TABLE cellSpacing=5 width= "100% ">
<tr>
<td id=demo11 vAlign=top width= "160 ">
<img src= "http://www.leyan.net/templates/sina/images/1.jpg ">
<img src= "http://www.leyan.net/templates/sina/images/2.jpg ">
<img src= "http://www.leyan.net/templates/sina/images/3.jpg ">
<img src= "http://www.leyan.net/templates/sina/images/4.jpg ">
</td>
<td id=demo12 vAlign=top> </td>
</tr>
</TABLE>
</DIV>
<DIV id=rolllink2> </DIV>
</DIV>
<SCRIPT>
var rollspeed=10
rolllink2.innerHTML=rolllink1.innerHTML
function Marquee(){
if(rolllink2.offsetTop-rolllink.scrollTop <=0)
rolllink.scrollTop-=rolllink1.offsetHeight
else{
rolllink.scrollTop++
}
}
var MyMar=setInterval(Marquee,rollspeed)
rolllink.onmouseover=function() {clearInterval(MyMar)}
rolllink.onmouseout=function() {MyMar=setInterval(Marquee,rollspeed)}
</SCRIPT>
<!--滚动代码结束-->
