Off-Screen Moving Objects Javascript - possible?

[pavlov]

Hello everybody.
I've this problem: I'm making a jpg moving horizontally from left to right in my page. I'd like to make it start moving from the left off-screen side. I tried using position negative values either defining the <style> of the img object or in the Javascript function that produces the image movement, but it doesn't work. The starting point from the images is always on screen.
Anybody can turn on the light??

Thanks!


This is the Js File:

var timer1;
 
function iecompattest(){
return (document.compatMode && document.compatMode!="BackCompat")? document.documentElement : document.body
}
 
function Chip(chipname,width,height){
this.named=chipname;
this.xx=(-495);
this.yy=208;
this.timer1=null;
}
 
function movechip(chipname){
if (document.getElementById){
eval("chip="+chipname);
if (window.innerWidth || window.opera){
 
pageY=window.pageYOffset;
pageH=window.innerHeight;
}
else if (document.body){
pageY=iecompattest().scrollTop;
pageH=iecompattest().offsetHeight;
}
 
 
while(chip.xx<250){
chip.xx=chip.xx+5;}
if (chip.xx<=420)
{
chip.xx=chip.xx+5;
}
else
chip.xx=chip.xx;
document.getElementById(chip.named).style.left=chip.xx+"px";
 
 
 
chip.timer1=setTimeout("movechip('"+chip.named+"')",50);
}

while(chip.xx<250){
chip.xx=chip.xx+5;}

would loop until 250, so xx can never be negative.
