What steps should be taken to ensure that the GD Library is properly integrated and functioning for JPEG image manipulation in PHP?

To ensure that the GD Library is properly integrated and functioning for JPEG image manipulation in PHP, you need to make sure that the GD extension is enabled in your PHP configuration. You can do this by checking your php.ini file and ensuring that the line `extension=gd` is uncommented. Additionally, you may need to install the GD Library if it is not already included in your PHP installation. 

// Check if the GD extension is enabled
if (!extension_loaded('gd')) {
    die('GD extension is not enabled. Please enable it in your php.ini file.');
}
