Are there best practices for resizing and storing images in PHP to ensure efficient loading and display on web pages?

When resizing and storing images in PHP for efficient loading and display on web pages, it's important to consider using libraries like GD or Imagick for image manipulation. Additionally, it's recommended to store different sizes of images for various devices (e.g., desktop, mobile) to optimize loading speed. Finally, make sure to compress images using tools like JPEGoptim or PNGquant to reduce file size without sacrificing quality. 

// Example code snippet using GD library to resize and store images
function resizeImage($source, $destination, $width, $height) {
    list($originalWidth, $originalHeight) = getimagesize($source);
    $image = imagecreatefromjpeg($source);
    $resizedImage = imagecreatetruecolor($width, $height);
    imagecopyresampled($resizedImage, $image, 0, 0, 0, 0, $width, $height, $originalWidth, $originalHeight);
    imagejpeg($resizedImage, $destination, 80); // 80 is the image quality
    imagedestroy($image);
    imagedestroy($resizedImage);
}

// Usage
resizeImage('original.jpg', 'resized.jpg', 300, 200);
