        $source = "https://shorebread.com/wp-content/uploads/2016/07/kitty-cat-reaching_138482216-2000x500.jpg";
        $dimension = getimagesize($source);
        $width = $dimension[0];

Because: user agent blocking?? How did you debug the second resource to be available for remote access? — mario, Oct 01 '17 at 04:39

It could be that the website doesn't allow "hot-linking" or that it blocks PHP's user agent.

If you try getting the data from the URL you will get a HTTP/1.1 403 Forbidden response:

php > $dimension = getimagesize($source);
PHP Warning:  getimagesize(https://shorebread.com/wp-content/uploads/2016/07/kitty-cat-reaching_138482216-2000x500.jpg):        
 failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden

 in php shell code on line 1

If you download the image first, and do the same from disk it works:

php > $dimension = getimagesize("kitty-cat-reaching_138482216-2000x500.jpg");
php > print_r($dimension);
Array
(
    [0] => 2000
    [1] => 500
    [2] => 2
    [3] => width="2000" height="500"
    [bits] => 8
    [channels] => 3
    [mime] => image/jpeg
)

So it is not that getimagesize doesn't work on all images. It couldn't download the image itself.

how to download image from site that blocks PHP's user agent ? — สุทธการ ทวีบุญล้น, Oct 01 '17 at 06:37
You can use `ini_set` before making any requests. See [this answer](https://stackoverflow.com/questions/8974742/change-user-agent-using-php). — Eduardo Romero, Oct 01 '17 at 19:57
