[Foundation-l] Ilustrating contemporary art articles without permission images

[Teofilo Folengo]

Until now, the scarce contemporary art articles featuring illustrations at
all on the French Wikipedia have been those using
permissions-to-Wikipedia-only, for example :
http://fr.wikipedia.org/wiki/Kim_Prisu


Supposing that permission images will no longer be allowed on any Wikimedia
project worldwide, how can we illustrate such articles, in the case of
artists whose art is a way of earning a living and who are therefore
unlikely to suscribe CC-BY-SA or GFDL licences ?

A user who wrote an article on Contemporary African Art says he is in touch
with African artists and able to take pictures. He asks what sort of
agreement should be made with the artists before publishing on Wikipedia :
http://fr.wikipedia.org/wiki/Wikip%C3%A9dia:Le_Bistro_multim%C3%A9dia/semaine_6_2007#images_d.27art

What should I answer him ?
