title: How to increase the height by the top of an image and keep the bottom fixed?
body: <p>I want resize an image HTML with jQuery.</p>
  
  <p>It's easy <code>elt.css({height: '42px'})</code>, but my problem is the magnification of the image is at the bottom, ie the top of the image does not move and it's the bottom that stretches or shortcut.</p>
  
  <p>Like here : <a href="http://jsfiddle.net/763wumr0/" rel="nofollow">http://jsfiddle.net/763wumr0/</a></p>
  
  <p>EDIT with absolute: <a href="http://jsfiddle.net/763wumr0/12/" rel="nofollow">http://jsfiddle.net/763wumr0/12/</a></p>
  
  <p>I'd like to do it the other way! The bottom of the image is fixed and that's the top of the image that increases or decreases.</p>
  
  <p>How can I do that?</p>
  
  <p>thx.</p>
