I haven’t included any demo files or images with the slider. However if you look inside you’ll see the html, and gallery content which are samples from the plugin author himself. The documentation on how to use the slider is also available inside of the plugin folder/zip.
You can take a look here and use try the import file that I used – https://appfinite.com/topic/demo-content-available/ …but I’m not sure if that will work for you or not.
