Nette\Image::fromFile – stále hlásí ''Image is not valid."

Na zkoušku tu máte tento kod:

		$urls = array(
			'http://www.dpscomputing.com/blog/wp-content/uploads/2012/03/php.jpg',
			'http://upload.wikimedia.org/wikipedia/commons/2/27/Crystal_Clear_mimetype_php.png',
			'http://www.netclues.ky/upimages/php.gif',
		);

		foreach ($urls as $url) {

			$image = \Nette\Image::fromString(file_get_contents($url));
			$image->save($_SERVER['DOCUMENT_ROOT'] . '/fromString-' . md5($url) . substr($url, strrpos($url, '.')));

		}

		foreach ($urls as $url) { // Zde to nikdy neprojde

			$image = \Nette\Image::fromFile($url); // Image is not valid
			$image->save($_SERVER['DOCUMENT_ROOT'] . '/fromFile-' . md5($url) . substr($url, strrpos($url, '.')));

		}

Nette: Poslední github verze.

Nevíte, kde by mohl být chyba a jak to řešit?
