Файл в корневой директории WP

<code php>
<?php
        
        // Set $to as the email you want to send the test to.

$to = "you@yourdomain.com" ;

$headers = '' ;

      // Load WP components, no themes.

define ('WP_USE_THEMES', false);

require('wp-load.php');

     // send test message using wp_mail function.

$sent_message = wp_mail( $to, $subject, $message, $headers);

     //display message based on the result.

if ( $sent_message ) {

    return ($ru["ru_$index.tv_sec"]*1000 + intval($ru["ru_$index.tv_usec"]/1000))
     -  ($rus["ru_$index.tv_sec"]*1000 + intval($rus["ru_$index.tv_usec"]/1000));

Альтернативно для работы с миниатюрами [[https://developer.wordpress.org/cli/commands/media/regenerate/|можно использовать wp-cli]].
