What is the purpose of using natsort() in the PHP code provided for the image gallery?

The purpose of using natsort() in the PHP code for the image gallery is to sort the array of image file names naturally, which means the files will be sorted in a human-friendly way rather than purely alphabetical. This ensures that the images are displayed in a more logical order, such as 1, 2, 10 instead of 1, 10, 2. 

$files = glob("images/*.jpg");
natsort($files);

foreach ($files as $file) {
    echo '<img src="' . $file . '" alt="Image">';
}
