title: [PHP/JavaScript]: How to refresh a Captcha?
body: <p>I am showing Captcha in this way:</p>
  
  <pre><code>&lt;img src="ReturnCaptcha2.php" alt="CAPTCHA" width="100" height="50"&gt;
  </code></pre>
  
  <p>I have a hyperlink named "Reload" near it. I want to recall that PHP file without refreshing my page. Probably, AJAX is involved in it. Please assist.</p>
