What potential issues can arise when trying to access images from an external server in PHP?

One potential issue when trying to access images from an external server in PHP is that the server may block external requests for security reasons. To solve this, you can use cURL to make the request and retrieve the image data. 

<?php

$url = 'https://www.externalserver.com/image.jpg';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$imageData = curl_exec($ch);
curl_close($ch);

// Display the image
header('Content-type: image/jpeg');
echo $imageData;

?>
