1// $('img.photo',this).imagesLoaded(myFunction)
2// execute a callback when all images have loaded.
3// needed because .load() doesn't work on cached images
4
5// Modified with a two-pass approach to changing image
6// src. First, the proxy imagedata is set, which leads
7// to the first callback being triggered, which resets
8// imagedata to the original src, which fires the final,
9// user defined callback.

15// webkit fix from Oren Solomianik. thx!
16
17// callback function is passed the last image to load
18//   as an argument, and the collection as `this`
