Hey Washington Post!

Here's a tiny tweak to your awesome article about DC building heights

Here where you're swapping images of buildings, there's a flash to white between the swap, since one is going to 0 and the other is going to 1 and they don't always match up perfectly time-wise.

new_img.stop().fadeTo(400,1)
  .siblings('img').stop().fadeTo(400,0);

It's easy to remove this flash and to make the animation a bit smoother, by using the complete callback on fadeTo -

new_img.stop().fadeTo(400,1, function() {
    new_img.siblings('img').stop().fadeTo(400,0);
});

Try it out - nice work on this piece!
