Description:
------------
i am just trying to resize an image on my computer, using the gd library, imagecreatefrompng gives me this errorFatal 
i have 777 chmodded all directories and files
gd is the bundled gd library installed as a shared module
imagecreatefromjpeg, using exactly the same code works fine

Reproduce code:
---------------
$file = '/path/to/Screenshot.png';
	$path = '/var/www/html/images/temp.png';
	$type = mime_content_type($file);
	$i = imagecreatefrompng($file);
	list($width, $height) = getimagesize($file);

	if ($width > $height) $scale = $width / 260;

	else $scale = $height / 240;


	$imgWidth = round($width/$scale, 0);

	$imgHeight = round($height/$scale, 0);

	$newI = imagecreatetruecolor($imgWidth, $imgHeight);

	$bgColor = imagecolorallocate($newI, 51, 85, 204);

	imagefilledrectangle($newI, 0, 0, $imgWidth, $imgHeight, $bgColor);

	imagecopyresampled($newI, $i, 0, 0, 0, 0, $imgWidth, $imgHeight, $width, $height);	

	if ($type == 'image/jpeg') imagejpeg($finalImg, $path, 70);

	else if ($type == 'image/x-png' || $type == 'image/png') imagepng($finalImg, $path, 70);
header('Content-type: image/png');
	imagepng($path);

Expected result:
----------------
prints the newly resized and created image to the screen

Actual result:
--------------
