title: Replace broken twitter images with javascript?
body: <p>In most cases you can replace a broken image with some code that looks like this:</p>
  
  <pre><code>&lt;img src="image.jpg" onerror="this.onerror=null;this.src='default.jpg'"&gt;
  </code></pre>
  
  <p>However, it doesn't seem to work with broken twitter profile images like this:</p>
  
  <p><a href="http://a1.twimg.com/profile_images/52087244/Photo_26.jpg" rel="nofollow noreferrer">http://a1.twimg.com/profile_images/52087244/Photo_26.jpg</a></p>
  
  <p>Is this because it is returning 403 instead of 404? Is there any way to fix this?</p>
