Are there any common pitfalls to be aware of when working with GD library 2.0 in PHP?

One common pitfall when working with GD library 2.0 in PHP is not checking if the GD extension is enabled in the PHP configuration. This can lead to errors when trying to use GD functions. To solve this issue, you can check if the GD extension is enabled using the `extension_loaded` function before using any GD functions.

if (!extension_loaded('gd')) {
    die('GD extension is not enabled. Please enable the GD extension in your PHP configuration.');
}
