What is the best practice for dynamically loading images based on quality settings using PHP?

When dynamically loading images based on quality settings in PHP, it is best practice to use the GD library to manipulate the image quality before outputting it to the browser. This can help optimize the image size and loading time based on the desired quality level. 

<?php
// Set the quality level for the image
$quality = 75;

// Load the image file
$image = imagecreatefromjpeg('image.jpg');

// Output the image with the specified quality level
header('Content-Type: image/jpeg');
imagejpeg($image, null, $quality);

// Free up memory
imagedestroy($image);
?>
