Description:
------------
The below code is fine on PHP 5.4 but fails on PHP 5.5 (tested on 1and1 Linux servers and WAMP)

imagealphablending() reports a problem - boolean parameter for parameter 1 instead of resource - on PHP 5.5 but NOT on PHP 5.4

Test script:
---------------
<?php

$f = "test.png";

$img = imagecreatefrompng($f);
if (!$img)
{
	echo "Failed to open ".$f;
	exit;
}

imagealphablending($img, true);
imagesavealpha($img, true);
      
header("Content-Type: image/png");
imagepng($img,null,6);
imagedestroy($img);
exit;

?>
 


Expected result:
----------------
Script runs on php 5.4 and returns an image.
On 5.5 reports broken image depending on browser.

I can't reproduce this issue. If you can, please check the result
of imagecreatefrompng() explicitly, e.g. by

  var_dump($img = imagecreatefrompng($f));
