var images = []; 
 
document.body.querySelectorAll("#text")[0].addEventListener("input",render,false); 
function render(){ 
	var div = document.body.querySelectorAll("#preview")[0]; 
  var text = document.body.querySelectorAll("#text")[0].value; 
  images.map(function(el){ 
  	var img = "<img width='100px' src='"+el.data+"' />"; 
  	text = text.replace(el.textCode,img); 
     
  }); 
  div.innerHTML = text; 
} 
document.body.querySelectorAll("#text")[0].addEventListener("paste",function(event){ 
  var items = (event.clipboardData || event.originalEvent.clipboardData).items; 
  for (index in items) { 
    var item = items[index]; 
    if (item.kind === 'file') { 
      var blob = item.getAsFile(); 
      var reader = new FileReader(); 
      reader.onload = function(event){ 
      	images.push(new myimg(event.target.result)); 
  		document.body.querySelectorAll("#text")[0].value += images[images.length-1].textCode; 
      render(); 
      }; // data url! 
      reader.readAsDataURL(blob); 
    } 
  } 
}); 
 
function myimg(data){ 
	this.data = data; 
  this.textCode = "{image"+images.length+"}"; 
}
