This PR does not work correctly: #601 (comment)

[THenkeDE]

to bypass this you have to add a helper variable like

			$gdfunction = 'imagecreatefrom'.$type;
			$silenceGdfunction = $type === 'png';
			...
					// GD library
					$img = $silenceGdfunction ? @$gdfunction($file) : $gdfunction($file);

but i have no idea if silencing a method was, is oder ever will be a good decision.
