title: Redirect direct image urls requests and pass the original url value in the redirection
body: <p>Suppose I have someone (or Google Images) trying to access</p>
  
  <p><code>http://null.com/uploads/someimage.jpg</code> (actually any image in /uploads folder)</p>
  
  <p>I'd want htaccess to redirect the user to </p>
  
  <pre><code>http://null.com/page/
  </code></pre>
  
  <p>HOWEVER, I need to pass the original url (<code>http://null.com/uploads/someimage.jpg</code>) to the redirection target page as a POST string value which the target php page can use to do stuff with it</p>
  
  <p>Would it be possible to achieve that with htaccess?</p>
  
  <p>UPDATE - and also, it would be interesting to have this working only when the user agent is a human operated browser, not a bot such as google bot, in this way Google and other search engines can crawl images appropriately without the redirection</p>
