title: Prevent hotlinking image files
body: <p>I want to avoid hotlinking images. Basing of this answer: <a href="https://stackoverflow.com/questions/9408197/using-hotlink-prevention">stackoverflow answer</a> I've tried to add the next snippet code into <code>.htaccess</code> file:</p>
  
  <pre><code>RewriteEngine on
  RewriteCond %{HTTP_REFERER} !^$
  RewriteCond %{HTTP_REFERER} !^http://(www.)?itransformer.es/.*$ [NC]
  RewriteRule \.(gif|jpe?g|png|wbmp)$ htttp://itransformer.es [R,L]
  </code></pre>
  
  <p>but it is not working. When I try to access the images putting the path in the navigation bar, I can access. What am I doing wrong?</p>
