What steps should be taken to ensure that the GD Library is installed and activated for PHP to use functions like imagecreatefromjpeg() properly?

To ensure that the GD Library is installed and activated for PHP to use functions like imagecreatefromjpeg() properly, you need to first check if the GD Library is installed on your server. If it is not installed, you can install it using a package manager like apt-get or yum. Once the GD Library is installed, you need to activate it in your PHP configuration file by uncommenting the line extension=gd.so or extension=gd.dll depending on your operating system. 

// Check if GD Library is installed and activated
if (!extension_loaded('gd')) {
    echo "GD Library is not installed or activated";
} else {
    echo "GD Library is installed and activated";
}
