I am trying to access a web service that returns a jpeg image. It requires two variables, time_sent and user_id, in the URL## Heading ##.

Here is my code:

   $ch = curl_init();
   $options =  array(

            CURLOPT_URL => 'www.example.com/service/?time_sent=time&user_id=user',
            CURLOPT_HTTPHEADER => array('Authorization-Token:' . $api_key, 'Content-type: image/jpeg'),
            CURLOPT_ENCODING => "",
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_HTTPGET => true,
            CURLOPT_CONNECTTIMEOUT => 60,
            CURLOPT_TIMEOUT => 60

        );
    }
    curl_setopt_array($ch, $options);
    $response = curl_exec($ch);

    if(!curl_errno($ch)){
        curl_close($ch);
        $img = imagecreatefromstring($response);
        imagejpeg($img);
        imagedestroy($img);
    }
    else{
        curl_close($ch);
        return curl_error($ch);
    }

Here is my output:

Nothing really, that looks like a healthy JPG :) Send a 

header("Content-type: image/jpeg");

before doing imagejpeg($img); and it should work.
