title: jquery unbind and off does not work on image
body: <p>I'm trying to only execute the slide fade in of the image once when it detects that its being shown on the page. Things that I've tried:</p>
  
  <pre><code>$(this).unbind();
  $(this).unbind("scroll");
  $(this).off();
  $(this).off("scroll");
  </code></pre>
