Create a new folder in 'images' when installing module

Question

I'm working on a basic module to display an image carousel. The module itself works well, but what I want to do now is create a new folder called 'carousel' within the root 'images' folder when the module installs.

I've researched this a lot here (I apologise if this is a duplicate question) and from searches, but no matter what I try I can't get it to work.

I have this in the manifest file.

<scriptfile>script.php</scriptfile>

And I've created a script.php file. Here's what I have so far:

<?php
// No direct access to this file
defined('_JEXEC') or die;

  class mod_CarouselInstallerScript
  {
    function install($parent) 
    {
      $destination = JPATH_SITE.'/'."images";
      $folder_name = "carousel";
      JFolder::create($destination .'/'. $folder_name, 0755);
    }
  }
?>

I've tried various versions of this found here and in Joomla documentation.

What am I missing?

Thank you to @Lodder for providing a solution, very much appreciated.

@Lodder suggested my class name may be incorrect and said to try 'replacing class mod_CarouselInstallerScript with class mod_Rmg_carouselInstallerScript'.

I changed my class to mod_RRM_carouselInstallerScript which solved the problem.
