What are the potential CPU load implications of applying filters to images in PHP?

When applying filters to images in PHP, there can be potential CPU load implications, especially if working with large or numerous images. To mitigate this, you can optimize your code by using efficient algorithms, caching filtered images, and limiting the number of filters applied per image. 

// Example code snippet to optimize applying filters to images in PHP
$image = imagecreatefromjpeg('input.jpg');

// Apply filter
imagefilter($image, IMG_FILTER_GRAYSCALE);

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

// Free up memory
imagedestroy($image);
