Updating photos in Joomla extensions

Is anyone familiar with the Vinaora Slick Slideshow extension for Joomla?

How do you update photos in it? A web developer set this up for a client of mine and they need to update the photos now. I’m not finding where it can be done in the Joomla Control panel.

Might be best to go to the docs for that slideshow. Don’t know if this helps:
