/**
* Convert Uploaded Images to WebP Format
*
* This snippet converts uploaded images (JPEG, PNG, GIF) to WebP format
* automatically in WordPress. Ideal for use in a theme's functions.php file,
* or with plugins like Code Snippets or WPCodeBox.
*
* @package WordPress_Custom_Functions
* @author Mark Harris
* @link www.christchurchwebsolutions.co.uk
*
* Usage Instructions:
* - Add this snippet to your theme's functions.php file, or add it as a new
* snippet in Code Snippets or WPCodeBox.
* - The snippet hooks into WordPress's image upload process and converts
* uploaded images to the WebP format.
*
* Optional Configuration:
* - By default, the original image file is deleted after conversion to WebP.
* If you prefer to keep the original image file, simply comment out or remove
* the line '@unlink( $file_path );' in the wpturbo_handle_upload_convert_to_webp function.
* This will preserve the original uploaded image file alongside the WebP version.
