Hello,
I like the idea but this sound very very bad:
Anyone who is willing to contribute his images can open an account there and declare that the pictures are his own and that he is willing to release them either to the public domain or under cc-by-2.5
How can we check if the images are really there own and license under de license as stated.
This is a great way to place copyvios on Commons.
And a other problem, the images are not uploaded under the license he says. The are placed under the gfdl and cc-by-3.0 license See ya,
