title: How to lazy load images without altering img tags or HTML for dynamically (user) generated images
body: <p>I know there are plenty of ways to lazy load images, but is there a way to do it ultimately without modifying the <code>&lt;img&gt;</code> tags? </p>
  
  <p>The <a href="http://www.appelsiini.net/projects/lazyload" rel="nofollow">tool</a> that seems to be the most popular says it cannot be done. </p>
  
  <p>The HTML cannot be changed because it is used as input and cannot be altered unless the user does so.</p>
  
  <p>Appreciated.</p>
