umm we use Free art images on wikipedia.
[[Image:Heckert_GNU_white.svg]] for example.
I've just read the Free Art license. Are we not violating the following section?
"3. INCORPORATION OF ARTWORK
All the elements of this work of art must remain free, which is why
you are not allowed to integrate the originals (originals and
subsequents) into another work which would not be subject to this
license."
We are integrating the artwork into Wikipedia, which is not subject to
that license...
