Hi marleyman
Slideshow extensions typically include a significant amount of JavaScript, which can impact site performance. Instead of creating a standalone slideshow extension, we use the ACM module for this purpose. The ACM module is integrated into each of our templates.
We recommend exploring our template library https://www.joomlart.com/joomla/templates to find a template that includes a slideshow design that suits your needs.
If you have any further questions, feel free to reach out!
Best regards,
