title: How to change the name "data-original" attribute name in images with no ids
body: <p>Context: I am trying a workaround to the lazyload script that does not work well for my setup.</p>
  
  <p>I am not sure this is realistic but, this is what I have in mind:
  On a title section click, I want to change all the attributes of the images contained in the section (so the images show). </p>
  
  <p>From data-original to src.</p>
  
  <p>Here is were I am:</p>
  
  <pre><code>$('#s101').click(function(){
  
  var a = $('#b01').next().find('img').attr("data-original");
  
  // alert (a) // will give me the url of the attr. data-original: (http...)
  
  x = a.getAttribute("data-original");
  a.setAttribute("src", x);
  a.removeAttribute("data-original");
                            });
  </code></pre>
  
  <p>This does not work. Could you help?</p>
