Be clear WHY you're doing it. Don't be seen to be making money out of it. Get release forms signed. Know the privacy laws of that country. Be ready to answer some quite direct and concerned questions from the parents.

To be honest, it's a lot of bother and you're opening yourself up to some quite serious potential problems. I'd think twice, and then once again before doing it. It's a nice idea but riddled with difficulties.
