Why doesn't the thumbnail appear on the page?

Question

PHP

Everything used to work fine, but recently it stopped. Not sure why or how...

header('Content-type: image/jpeg');
        print_r(file_get_contents('https://cdn.discordapp.com/attachments/823254352025747466/823270819102195782/kartinka.jpg'));

Instead of a picture on the page, a stupidly white square is visible ...

Answer 1

check if the external link opens at all

print_r(get_headers('https://cdn.discordapp.com/attachments/823254352025747466/823270819102195782/kartinka.jpg', true));
