[Wikipedia-l] Wikipedia:Image use policy

[Guillaume Blanchard]

Bonjour,
I just finish to read [Wikipedia:Image use policy] but I didn't found the
information I searched.
Do we need to write the licence statute on a picture ?
All pictures I released for Wikipedia until now was marked on the
bottom-right by "Under GFDL".
I remeber someone tell me to do more that 1 year latter.
But main part of pictures I see on Wikipedia don't have such mark.
What is the policy about it ?
Regards,

Aoineko
