title: Google images: get large image URL from thumbnail URL
body: <p>Is there any way to build the URL of a medium/large/original image corresponding to a thumbnail URL returned by the <a href="https://developers.google.com/custom-search/json-api/v1/overview" rel="nofollow">Google Custom Search API</a>?</p>
  
  <p>In other words, from this thumbnail URL: </p>
  
  <blockquote>
    <p><a href="https://t3.gstatic.com/images?q=tbn:ANd9GcRYiGRk0xt6OXpRa3j7ySJNeATepTe7zaWzm1G6KpGAwpHePcTmYPYp6WI" rel="nofollow">https://t3.gstatic.com/images?q=tbn:ANd9GcRYiGRk0xt6OXpRa3j7ySJNeATepTe7zaWzm1G6KpGAwpHePcTmYPYp6WI</a></p>
  </blockquote>
  
  <p>is it somehow possible to find the URL of a bigger image?</p>
  
  <p>I tried to replace <code>tbn</code> (for 'thumbnail'?) in the <code>q</code> URL param by <code>medium</code>, <code>large</code>,... but without success.</p>
