Good day peeps!

I need some help figuring out how I can put a comment section underneath my gallery. It would be great if it's possible for people to react to my photo's. This is the page: http://traveltounravel.nl/portfolios/photography/
My Wordpress theme is PhotoMe and I asked support if it's possible with the theme, but they say it's only possible with a plug-in. Anyone knows a way to create a comment section? 

Thanks!!
