How can I render a remote image with php?

Question

Here's a jpg: https://i.sstatic.net/PIFN0.jpg

Let's say I'd like this rendered from /img.php?file_name=PIFN0.jpg

Here's how I'm trying to make this work:

/sample.php

<p>Here's my image:</p>
<img src="/img.php?file_name=PIFN0.jpg">

/img.php

<?php
    $url = 'https://i.sstatic.net/' . $_GET['file_name'];
    header('Content-type: image/jpeg');
    imagejpeg($url);
?>

I would expect /sample.php to show the image. But this doesn't work. All I get is a broken image. What am I doing wrong?

Answer 1

Use imagecreatefromjpeg:

<?php
    $url = 'https://i.sstatic.net/' . $_GET['file_name'];
    header('Content-type: image/jpeg');
    imagejpeg(imagecreatefromjpeg($url));
?>
