28 * Grab the page inner contents by calling the content function from the profile module directly,
29 * but move any image src attributes to another attribute name. This is because
30 * some browsers will prefetch all the images for the page even if we don't need them.
31 * The only ones we need to fetch are those for new page additions, which we'll discover
32 * on the client side and then swap the image back.
