Finally found a solution, posting it here just in case someone runs into the same issue, I have replaced the getimageresize() with this function:

function getimgsize($url, $referer = ”)
{
$headers = array(
‘Range: bytes=0-32768’
);

/* Hint: you could extract the referer from the url */
if (!empty($referer)) array_push($headers, ‘Referer: ‘.$referer);

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($curl);
curl_close($curl);

$image = imagecreatefromstring($data);

$return = array(imagesx($image), imagesy($image));

imagedestroy($image);

return $return;
}
