title: Secureimage in CodeIgniter
body: <p>So I wan't to use secureimage on CI coz' I don't want to use the default CAPTCHA helper since it doesn't have an audio option but I have a problem displaying the audio when using secureimage.</p>
  
  <p>I copied the whole secureimage folder that I downloaded from the site to the library of CI.</p>
  
  <p>Displaying the image is fine and also checking the inputted code. But my problem is displaying the audio file. I have no idea how to do it.</p>
  
  <p>Here is how I displayed the image and for checking (already used the secureimage library):</p>
  
  <pre><code>function captcha_image(){
      $img = new Securimage();
      return $img-&gt;show();
  }
  
  public function captcha_check(){
      $img = new Securimage();
      $input = $this-&gt;input-&gt;post('imagecode');
      $result = $img-&gt;check($input); 
  
  
      if($result)
          $message = "success";
      else
          $message = "try again";
  }
  </code></pre>
  
  <p>My view:</p>
  
  <pre><code>&lt;img src="&lt;?php echo site_url('form/captcha_image') ?&gt;" alt='captcha' /&gt;
  </code></pre>
