Are there any best practices to follow when manipulating images with PHP?

When manipulating images with PHP, it is important to follow best practices to ensure efficient processing and maintain image quality. Some best practices include using image libraries like GD or Imagick, optimizing images for web by compressing them, and handling errors properly to prevent any issues. 

// Example of resizing an image using GD library
$image = imagecreatefromjpeg('example.jpg');
$width = imagesx($image);
$height = imagesy($image);

$newWidth = 200;
$newHeight = ($height / $width) * $newWidth;

$newImage = imagecreatetruecolor($newWidth, $newHeight);
imagecopyresampled($newImage, $image, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);

imagejpeg($newImage, 'resized_example.jpg', 80);

imagedestroy($image);
imagedestroy($newImage);
