How can one use .htaccess to protect image folders or serve images outside the web root in PHP?

To protect image folders or serve images outside the web root in PHP, you can use .htaccess to restrict access to the image files or configure the server to serve images from a specific directory outside the web root. This can help prevent unauthorized access to your images and improve security.

# Place this .htaccess file in the image directory you want to protect
# Deny access to all files in this directory
<Files *>
    Order Deny,Allow
    Deny from all
</Files>
