What potential pitfalls should be avoided when using GDLib in PHP for image generation?

One potential pitfall when using GDLib in PHP for image generation is not properly sanitizing user input, which can lead to security vulnerabilities such as code injection. To avoid this, always validate and sanitize user input before using it to create or manipulate images. 

// Example of sanitizing user input before using it with GDLib
$user_input = $_POST['user_input'];

// Validate and sanitize user input
$sanitized_input = filter_var($user_input, FILTER_SANITIZE_STRING);

// Use the sanitized input to create or manipulate images with GDLib
