<div id=demo style=overflow:hidden;height:55;width:255;color:#ffffff><table align=left cellpadding=0 cellspace=0 border=0><tr>
<td id=demo1 valign=top><img src="images/flash8.gif"><img src="images/link/flashempire.gif"><img src="images/link/deskcity.gif"><img src="http://www.blueidea.com/logo.gif">

<script>
var speed=30
demo2.innerHTML=demo1.innerHTML
function Marquee(){
if(demo2.offsetWidth-demo.scrollLeft<=0)
demo.scrollLeft-=demo1.offsetWidth
else{
demo.scrollLeft++

var MyMar=setInterval(Marquee,speed)
demo

<script>
var speed=30
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)}
