title: Google Custom Search API for square images
body: <p>I'm looking for a way to specify that the images returned by the Google Custom Search API have a square format.</p>
  
  <p>I've tried tbs=iar:s (because I've read <a href="https://stackoverflow.com/questions/13946868/using-the-custom-search-api-rest-json-to-search-for-square-images">Using the Custom Search API (REST JSON) to search for square images</a>), but it doesn't work.</p>
  
  <p>Have you an idea please ?</p>
