Here is my code:

 
function OrbCreator(){
  var b;
 b=document.createElement("<img src='./images/Orb.png' style='position:absolute; display:none; left:10000px; top:0px; width:"+(2*Orbsize)+"px; height:"+(2*Orbsize)+"px;'>");
 this.is=b.style;
  this.src=b.src;
  this.move=moveOrb;
  document.getElementById("container").appendChild(b);
 this.is.display='block';
}
 
function moveOrb(x,y,z){
  this.is.width=2*Os;
  this.is.height=2*Os;
  this.is.left=x-Os;
  this.is.top=y-Os;
  this.is.zIndex=z;
  if(this.renew==true){
   this.renew=false;
   this.src="./images/NewImage.png";
  }
}

What am I doing wrong?

Using document.createElement like that doesn't work in Firefox.

You again!!!, yeah but that is perfunctory... immediate prob is the image update.

I can't tell much from that code. It depends on what "this" is referring to. Are these functions being be used as constructors, or being triggered by an event of some sort?

Orb[a].move(px[a],py[a],pz[a]); Have you looked at the site, that should make it much clearer than perusing tons of code... but if you like, I can post the entire script?
var Orb=new Array();

Sorry, the whole page isn't working for me in Firefox, and I don't really know what that means.

Maybe if you make a really simple example of what isn't working you'll be able to figure it out.
