You should be able to do it in server side. If you want to do it in client side you can try like this. But not sure about browser support.

var _URL = window.URL || window.webkitURL; 
$("#file").change(function (e) { 
  var file, img; 
  if ((file = this.files[0])) {
   img = new Image();
   img.onload = function () { 
      alert(this.width + " " + this.height);
   }; 
   img.src = _URL.createObjectURL(file);
  }
 });

Note: I have taken plane js approach. Not using package collection.
