title: Converting from server image URL to absolute address
body: <p>I guess this is a simple question but I really can't find anything that would help me.</p>
  
  <p>I'm using an image download script and for that I need an image URL that looks like:
  "/home/clients/websites/w_apo/public_html/apo/wp-content/uploads/2012/05/Beautiful.jpg"
  [type1]</p>
  
  <p>but what I have is:
  "http://www.apo.com/wp-content/uploads/2012/05/Beautiful.jpg"
  [type2]</p>
  
  <p>I tried to write a function that returns the URL of type 1 to the URL of type 2 but it doesn't work all that great.
  This is how it looks:</p>
  
  <pre><code>function relativeToServerAddress($relativeURL) {
      $paths = explode('wp-content/', $relativeURL);
      $thePath = getcwd()."/wp-content"."/".$paths[1];
      return $thePath;
  }
  </code></pre>
  
  <p>Is there any better way to do this? I tried to find a predefined function but failed.</p>
  
  <p>Thanks</p>
