For https sites one should change private $api = 'http://chart.apis.google.com/chart'; to

either

private $api = 'https://chart.apis.google.com/chart';

or

private $api = '//chart.apis.google.com/chart';

To satisfy Google Pagespeed, which is complaining about "Image elements do not have explicit width and height", one can change:

$content = '<img src="' . $qrc->get_link() . '"'.$tribs.' alt="QR code" />';

to

 $content = '<img src="' . $qrc->get_link() . '"'.$tribs.' alt="QR code" width=".$width." height=".$height." />';
