How can the code snippet provided in the forum thread be optimized for better image quality when creating thumbnails?

The issue with the code snippet provided in the forum thread is that it uses a low-quality image resizing algorithm, resulting in poor image quality for thumbnails. To optimize for better image quality, we can use a more advanced image resizing library like "Imagine" that provides better interpolation methods for resizing images.

// Using Imagine library for better image quality
require 'vendor/autoload.php';

use Imagine\Image\Box;
use Imagine\Image\Point;
use Imagine\Gd\Imagine;

$imagine = new Imagine();
$image = $imagine->open('original_image.jpg');
$thumbnail = $image->thumbnail(new Box(100, 100));

$thumbnail->save('thumbnail.jpg');
