Different as the images are not stored but formed.Plus, this doent seem to work — , Jun 28 '16 at 11:40
Have you tried actually retrieving the URL and checked that you get image data? Have you tried using imagecreatefromstring to read the image? Have you used finfo_buffer to check the type of the data returned? Have you tried fetching the data to a file first, then read it with imagepng? Are you able to retrieve other files from the same host? — MatsLindh, Jul 03 '16 at 13:15

Example

$url1 = "https://imageare.com/nc/Aud/tr.phptrack=426413219_chan1.wav&ignorable_duration=1.0";
$png_image = imagecreatefromfile($url1);
function imagecreatefromfile($filename) {
    if(!file_exists($filename)) {
        throw new InvalidArgumentException('File "'.$filename.'" not found.');
    }
    switch(strtolower(pathinfo($filename, PATHINFO_EXTENSION))) {
        case 'jpeg':
        case 'jpg':
            return imagecreatefromjpeg($filename);
        break;

        case 'png':
            return imagecreatefrompng($filename);
        break;

        case 'gif':
            return imagecreatefromgif($filename);
        break;

        default:
            throw new InvalidArgumentException('File "'.$filename.'" is not valid jpg, png or gif image.');
        break;
    }
}

To merge two images like shown here and assuming that images are in png .You might need to use following code:

$url1=https://imageare.com/nc/Aud/tr.php?track=426413219-.wav&ignorable_duration=1.0
$url2=https://imageare.com/nc/Aud/tr.phptrack=426413219_chan1.wav&ignorable_duration=1.0
$dest = imagecreatefrompng($url1);
$src = imagecreatefrompng($url2);
imagecopymerge($dest, $src, 0, 0, 0, 0, 500, 100, 90);

The following can be used to output image to browser

header('Content-Type: image/png');
imagepng($dest);
