滚动图片左移改为右移

[feishanm]

有哪位知道将下面的代码改为：图片向右移动吗？
<script>
var Picspeed=15
demo2.innerHTML=demo1.innerHTML
function Marquee1(){
if(demo2.offsetWidth-demo.scrollLeft<=0)
demo.scrollLeft-=demo1.offsetWidth
else{
demo.scrollLeft++
}
}
var MyMar1=setInterval(Marquee1,Picspeed)
demo.onmouseover=function() {clearInterval(MyMar1)}
demo.onmouseout=function() {MyMar1=setInterval(Marquee1,Picspeed)}
</script>

function Marquee(){
if(demo.scrollLeft<=0)
demo.scrollLeft+=demo2.offsetWidth
else{
demo.scrollLeft--
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
