Can I use a URL as the source for imagecreatefromjpeg() without enabling fopen wrappers?
You can download the file using cURL then pipe the result into imagecreatefromstring.
Example:
$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $imageurl); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // good edit, thanks! curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1); // also, this seems wise considering output is image. $data = curl_exec($ch); curl_close($ch); $image = imagecreatefromstring($data);
You could always download the image (e.g. with cURL) to a temporary file, and then load the image from that file.
