What are the benefits of creating a PHP script to handle image retrieval and display based on ID, as opposed to directly linking to the image file?

When retrieving and displaying images based on ID, using a PHP script allows for more control and flexibility. This approach enables you to perform additional checks, such as user authentication or image manipulation, before serving the image. It also helps to prevent direct access to the image files, providing an added layer of security. 

<?php
// Retrieve image based on ID
$imageId = $_GET['id'];

// Perform necessary validation and authorization checks here

// Set appropriate headers
header("Content-Type: image/jpeg");

// Output the image file
readfile("path/to/images/{$imageId}.jpg");
?>
