What are the best practices for optimizing performance and managing storage when dealing with images in PHP?

When dealing with images in PHP, it is important to optimize performance and manage storage efficiently. One way to achieve this is by resizing images to the appropriate dimensions before storing them. This can help reduce the file size and improve loading times on web pages. 

// Example code to resize and store an image using PHP
$sourcePath = 'path/to/source/image.jpg';
$destinationPath = 'path/to/destination/image.jpg';
$maxWidth = 800;
$maxHeight = 600;

list($width, $height) = getimagesize($sourcePath);
$ratio = $width / $height;

if ($width > $maxWidth || $height > $maxHeight) {
    if ($maxWidth / $maxHeight > $ratio) {
        $maxWidth = $maxHeight * $ratio;
    } else {
        $maxHeight = $maxWidth / $ratio;
    }
    $newImage = imagecreatetruecolor($maxWidth, $maxHeight);
    $sourceImage = imagecreatefromjpeg($sourcePath);
    imagecopyresampled($newImage, $sourceImage, 0, 0, 0, 0, $maxWidth, $maxHeight, $width, $height);
    imagejpeg($newImage, $destinationPath);
} else {
    copy($sourcePath, $destinationPath);
}
