上面的这段代码是让图片向上滚动，但是一开始图片就向上滚动，我想要图片一开始不滚动，停留3000ms以后再滚动，我对js不太熟，请教大家要如何修改这段代码才能达到我想要的效果

 <script>
function $(element){
if(arguments.length>1){
for(var i=0,length=arguments.length,elements=[];i<length;i++){
elements.push($(arguments[i]));
}
return elements;
}
if(typeof element=="string"){
return document.getElementById(element);
}else{
return element;
}
}
var Class={
create:function(){
return function(){
this.initialize.apply(this,arguments);
}
}
}
Function.prototype.bind=function(object){
var method=this;
return function(){
method.apply(object,arguments);
}
}
var Scroll=Class.create();
Scroll.prototype={
initialize:function(element,height){
this.element=$(element);
this.element.innerHTML+=this.element.innerHTML;
this.height=height;
this.maxHeight=this.element.scrollHeight/2;
this.counter=0;
setTimeout(this.delay(this),3000);//////////////////延迟3000ms后执行

},
delay:function(self){//////////////////////////////增加该方法执行延时，其他不用改动
  return function(){
  self.scroll();
  self.timer="";
  self.element.onmouseover=self.stop.bind(self);
  self.element.onmouseout=function()  {self.timer=setTimeout(self.scroll.bind(self),1000);}.bind(self);
  }
},
scroll:function(){
if(this.element.scrollTop<this.maxHeight){
this.element.scrollTop++;
this.counter++;
}else{
this.element.scrollTop=0;
this.counter=0;
}
if(this.counter<this.height){
this.timer=setTimeout(this.scroll.bind(this),20);
}else{
this.counter=0;
this.timer=setTimeout(this.scroll.bind(this),3000);
}
},
stop:function(){

var myscroll=new Scroll("myscroll",50);
</script>
