How can PHP scripts be optimized for image manipulation tasks to improve performance and image quality?

To optimize PHP scripts for image manipulation tasks, it is important to use efficient image processing libraries like GD or Imagick, avoid unnecessary image resizing or processing, and cache processed images to reduce server load and improve performance. 

// Example of optimizing image manipulation tasks using Imagick
$image = new Imagick('input.jpg');
$image->resizeImage(500, 0, Imagick::FILTER_LANCZOS, 1);
$image->writeImage('output.jpg');
$image->destroy();
