Hello, Jernej!
It seems to me that if any materials were developed for social media, they would not usually end up on Wikimedia Commons :) Their life span is too short - to attract attention, and (maybe) sometimes they will even be on the border of copyright violation... and even out of scope.
Maybe something like this fact sheet will be useful?
(You can also post parts of it, like separate facts, like:
- Slovenia has xxx monuments, and only xx are illustrated (or some other locally relevant statistics) etc, to motivate people and make them aware)
Especially as you are doing your first contest...
З повагою / Best regards,
