Well, after http://fr.wikipedia.org/wiki/Projet:Impression this project has been started (see also discussion on meta forum, http://meta.wikimedia.org/wiki/Wikimedia_Forum#Alleged Commercialisation of the French Wikipedia) I decided not to upload any images on Commons with resolution higher than 800x600 any more. (This resolution is perfectly fine to illustrate the articles but is substandard for any commercial use). One of the stewards, MaxSem, has left all Wikimedia projects because of this initiative. Therefore, I do not quite understand what we are talking about.
