[Plugin: NextGEN Gallery] Top 3 most facebook likes within NextGen Gallery plugin WordPress

Hello everyone,

I have build a like button per foto in NextGen Gallery in WordPress via the next tutorial: https://itc.webmaasters.com/nextgen-gallery-with-facebook-and-twitter-wordpress-tutorial-or-hack/#.UDdgz9ZlQUo

My purpose now is to make a list of the Top 3 most liked fotos.

I have a demo over here: https://www.fotostudio87.nl/fotowedstrijd-2/

Does anybody has any idea how to accomplish a Top 3 list of the most liked foto’s?

Greetings,

Joni Fleischer
