Onetone Gallary doesn't work

Hi,
Please provide your site link

My gallery doesn’t work as well.
https://www.movemefilm.com

nevermind. it’s working now

Ok I am a worse nob – I am looking for the area where I can actually put in my photos and how do you get rid of the background video or insert a new one? – are these all in the editing pages? I was hoping there was in interface in the options – I dont see an option area for this…

Thanks

As per the instructions:
You can install the “Photo Gallery” plugin, make the required customizations for the view in the shortcode in advance to adding in the Sctions Content area.

It took me a while to find this little piece of info.
