putting pictures into a Gravit page

Hi,

I am having trouble inserting picture into a page of mine using the Gravit theme. My site is: https://doyouneedawriter.com

and on the examples page https://doyouneedawriter.com/examples I would like to show 9 different pictures and be able to organize the layout of them.

Does anyone know if this is possible and if so, how I go about doing it?

Thanks

Patrick
