images loaded plugin

jquery.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`
