1、建立duilian.js页面，内容如下

//左边
var left_img='<a title=圆点视线 target=_blank href=http://www.is686.com/list.php?u=loveflash><img border=0 src=/web/UploadFiles/200512/20051222172653862.gif width=100 height=100></a><br><br><a title=圆点视线 target=_blank href=http://w2.001122.com/list.php?u=loveflash><img border=0 src=/web/UploadFiles/200512/20051222172653569.gif width=100 height=100></a>';

//右边
var right_img='<a title=圆点视线 target=_blank href=http://www.is686.com/list.php?u=loveflash><img border=0 src=/web/UploadFiles/200512/20051222172653569.gif width=100 height=100></a><br><br><a title=圆点视线 target=_blank href=http://w2.001122.com/list.php?u=loveflash><img border=0 src=/web/UploadFiles/200512/20051222172653862.gif width=100 height=100></a>';
 var delta=0.05
 var collection;
 function floaters() {
  this.items = [];
  this.addItem = function(id,x,y,content)
      {
     document.write('<DIV id='+id+' style="Z-INDEX: 10; POSITION: absolute;  width:80px; height:60px;left:'+(typeof(x)=='string'?eval(x):x)+';top:'+(typeof(y)=='string'?eval(y):y)+'">'+content+'</DIV>');
     
     var newItem    = {};
     newItem.object   = document.getElementById(id);
     newItem.x    = x;
     newItem.y    = y;

     this.items[this.items.length]  = newItem;
      }
  this.play = function()
      {
     collection    = this.items
     setInterval('play()',10);
      }
  }
  function play()
  {

   for(var i=0;i<collection.length;i++)
   {
    var followObj  = collection[i].object;
    var followObj_x  = (typeof(collection[i].x)=='string'?eval(collection[i].x):collection[i].x);
    var followObj_y  = (typeof(collection[i].y)=='string'?eval(collection[i].y):collection[i].y);

    if(followObj.offsetLeft!=(document.body.scrollLeft+followObj_x)) {
     var dx=(document.body.scrollLeft+followObj_x-followObj.offsetLeft)*delta;
     dx=(dx>0?1:-1)*Math.ceil(Math.abs(dx));
     followObj.style.left=followObj.offsetLeft+dx;
     }

    if(followObj.offsetTop!=(document.body.scrollTop+followObj_y)) {
     var dy=(document.body.scrollTop+followObj_y-followObj.offsetTop)*delta;
     dy=(dy>0?1:-1)*Math.ceil(Math.abs(dy));
     followObj.style.top=followObj.offsetTop+dy;
     }
    followObj.style.display = '';
   }
  } 
  
 var theFloaters  = new floaters();
 theFloaters.addItem('followDiv1','document.body.clientWidth-110',170,''+right_img+'');
 theFloaters.addItem('followDiv2',10,170,''+left_img+'');
 theFloaters.play();

2、在需要的地方调用：<script language="Javascript" src="http://xxxxxxxxxx/duilian.js"></script>
