title: Which image php extension install for dompdf
body: <p>I am trying to create a pdf with <a href="http://code.google.com/p/dompdf/" rel="nofollow">dompdf</a> but I get this error when it is trying to add an image.</p>
  
  <pre><code>Uncaught exception 'DOMPDF_Exception' with message 'Function imagecreatefromgif() not found.  Cannot convert gif image: E:\APBPEVALUACIONDES/imagenes/header.gif.  Please install the image PHP extension.' in E:\APBPEVALUACIONDES\dompdf6\include\cpdf_adapter.cls.php:470
