What are some potential pitfalls to be aware of when resizing images using PHP's GD library?

One potential pitfall when resizing images using PHP's GD library is the loss of image quality. To avoid this, it is important to use the appropriate interpolation method when resizing images. The `imagecopyresampled()` function can be used with the `IMG_BICUBIC` interpolation method to achieve better image quality when resizing. 

// Load the original image
$original_image = imagecreatefromjpeg('original.jpg');

// Define the dimensions for the resized image
$new_width = 200;
$new_height = 150;

// Create a new image with the specified dimensions
$resized_image = imagecreatetruecolor($new_width, $new_height);

// Resize the original image using imagecopyresampled() with IMG_BICUBIC interpolation
imagecopyresampled($resized_image, $original_image, 0, 0, 0, 0, $new_width, $new_height, imagesx($original_image), imagesy($original_image));

// Save the resized image
imagejpeg($resized_image, 'resized.jpg');

// Free up memory
imagedestroy($original_image);
imagedestroy($resized_image);
