inline background versus adding a div

[jasonmit]

Great stuff, just nit picking on how it could be done without adding additional elements into the DOM.

Hide the targeted img tags and hook up onload callbacks for each of the images, which will be used to grab the height when their finished.

Remove the src and move it onto an inlined styled background. Set the img height to 0 and the margin-bottom to the cached height value from the onload callback. Now begin to emulate the comcast-effect by increasing the height and decreasing the margin-bottom.
