How can the GD Lib or GD2 Lib be activated and verified on a web server for PHP image manipulation?

To activate and verify the GD Lib or GD2 Lib on a web server for PHP image manipulation, you can check if the GD extension is enabled in your PHP configuration. You can do this by creating a PHP file with the phpinfo() function and checking if GD is listed. If it is not enabled, you can enable it by installing the necessary GD libraries on your server.

<?php
// Create a PHP file (e.g., gd_check.php) with the following code
phpinfo();
// Check if GD is listed in the output
?>
