Now, where are the rules of the game?

Why do I ask? Easy - I have suffered too many deletes from Commons of images that I created of work of arts. I have stopped submitting much at all to Commons, since I cannot be sure that I am submitting permissible work.
So, this competition is going to be populated with people (like me) who don't know that I cannot take a picture of art work in a temporary exhibition and submit it to Commons.
I know that the rules for Wikipedia are different, which was was why I asked about the primary submission site - would it be Commons or Wikipedia. FLICKR does not have any GFDL options: everything is submitted under Creative Commons Licence, or full copyright. Three of the options are incompatible with Commons:
Attribution-NonCommercial-ShareAlike Creative Commons

A scavenger hunt works best where there is some freedom to interpret the rules, bend them, extend them etc.
And have fun.
