What are the potential pitfalls of using GDlib functions for image manipulation in PHP?

One potential pitfall of using GDlib functions for image manipulation in PHP is the lack of error handling, which can lead to unexpected behavior or crashes if not properly handled. To mitigate this issue, it is important to check for errors after each GDlib function call and handle them accordingly. 

// Example of error handling with GDlib functions in PHP
$image = imagecreatefromjpeg('image.jpg');

if (!$image) {
    die('Error loading image');
}

// Perform image manipulation operations here

// Output the final image
header('Content-Type: image/jpeg');
imagejpeg($image);

// Free up memory
imagedestroy($image);
