 * Hello !
 * いつもお世話になっております。
 * I was wondering what’s the best way to customize the characters inside the image.
   
   At the moment, I’m simply editing the variable inside the plugin code.
 *     ```
       public function __construct() {
       		/* Characters available in images */
       		$this->chars = '0123456789';  /* <- EDITED THIS PART */
       ```
   
 * Since this would probably get replaced at any updates, is there a way to customize
   this inside my functions.php ?
 * Thanks in advance.

 * if you use contact form 7 you should use the new recaptcha from google, as written
   in the description. especially the usability and security is better than really
   simple captcha.

 * Thanks for the quick reply.
 * I agree with you 100%, but the website owner specifically asked me for a regular
   numbered captcha.
    Thanks anyway !
