title: PHP/GD : Better Gaussian blur
body: <p>I want to blur an image with GD library, unfortunately the GAUSSIAN_BLUR effect that GD gives isn't enough and i want something being more <em>blurrish</em></p>
  
  <pre><code>&lt;?php $im = imagecreatefrompng($_GET['image']);
  if($im &amp;&amp; imagefilter($im, IMG_FILTER_GAUSSIAN_BLUR))
  {
    header('Content-Type: image/png');
      imagepng($im);
  }
  else
  {
      echo 'fail';
  }
  
  imagedestroy($im);
  </code></pre>
  
  <p>I want something like this or at least near it.
