Gregory:
I've received three replies back so far, one
indicating that her work
was indeed "free for any use" but two who complained that stock.xchng
isn't clear in their licensing and that their work isn't PD. One of
them said his work is cc-by-nc-sa,
That directly contradicts the terms they uploaded them under, which
allow for commercial use. To say we have to contact every individual SXC
user is like saying we have to contact people uploading their work as
CC-BY-SA and make sure that they really "meant it." I disagree with that
notion. If people explicitly upload images with "no usage restrictions",
then that's what I think we should refer to, unless these people then
contact us and complain about the usage.
