imagesLoaded() jquery plugin - adding unbind for load event

imagesLoaded.js

// $('img.photo',this).imagesLoaded(myFunction)
// execute a callback when all images have loaded.
// needed because .load() doesn't work on cached images

// mit license. paul irish. 2010.
// webkit fix from Oren Solomianik. thx!

// callback function is passed the last image to load
//   as an argument, and the collection as `this`


$.fn.imagesLoaded = function(callback){
  var elems = this.filter('img'),
      len   = elems.length,
      blank = "data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///ywAAAAAAQABAAACAUwAOw==";
      
  elems.bind('load.imagesLoaded',function(e){
    if (--numOfElems <= 0 && e.target.src !== blank){ callback.call(elems,e.target); $(elems).unbind('load.imagesLoaded'); }
  }).each(function(index, e){
     // cached images don't fire load sometimes, so we reset src.
     if (e.complete || e.complete === undefined){
        var src = e.src;
        // webkit hack from http://groups.google.com/group/jquery-dev/browse_thread/thread/eee6ab7b2da50e1f
        // data uri bypasses webkit log warning (thx doug jones)
        e.src = blank;
        e.src = src;
     }  
  }); 

  return this;
};

muche better - but u need to correct or len or numOfElems
