What are some potential pitfalls when using the GD Library in PHP for image resizing and quality optimization?

One potential pitfall when using the GD Library in PHP for image resizing and quality optimization is the loss of image quality due to improper compression settings. To avoid this, make sure to set the compression quality parameter appropriately when saving the image. 

// Resize and save image with proper compression quality
$image = imagecreatefromjpeg('input.jpg');
$newImage = imagescale($image, 200, 200);
imagejpeg($newImage, 'output.jpg', 90); // Set quality parameter to 90 for better image quality
imagedestroy($image);
imagedestroy($newImage);
