title: PNG Transparency with PHP
body: <p>Hey having some trouble trying to maintain transparency on a png when i create a thumbnail from it, anyone any experience with this? any help would be great, here's what i am currently doing:</p>
  
  <pre><code>$fileName= "../js/ajaxupload/tees/".$fileName;
  
  list($width, $height) = getimagesize($fileName);
  
  $newwidth = 257;
  $newheight = 197;
  
  $thumb = imagecreatetruecolor($newwidth, $newheight);
  imagealphablending($thumb, true);
  $source = imagecreatefrompng($fileName);
  imagealphablending($source, true);
  
  imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
  
  imagesavealpha($thumb, true);
  imagepng($thumb,$newFilename);
  </code></pre>
