title: Animate the image of a hand to make it wave using jQuery
body: <p>I'd like to animate the hand of a character to make it like if it was waving at somebody, using jQuery.
  I've tried to swap 2 images (a hand poiting to the left and a hand pointing to the right). But it's not very smooth...
  Is there a better solution? I've also tried to use a jQuery plugin to rotate the image, but I couldn't find a plugin which works (&amp; compatible with IE8).
  Thanks for your help!</p>
