[Pedro Sanchez]

See http://en.wikipedia.org/wiki/Image:Mondrian_CompRYB.jpg
is it fair use?
it's used on a bazillion userpages

How about
http://en.wikipedia.org/wiki/Image:Piet_Mondrian.jpg
could fair use be argued on that? it wasn't used on Piet Mondrian (and
his works have already been exemplified)

how about using them in galleries?

I don't think guernica is allowed on [[Terror bombing]] under fair use
http://en.wikipedia.org/w/index.php?title=Terror_bombing&diff=prev&oldid=100791691

How about [[Aerial bombing of cities]] ?
Does fair use REALLY cover its use on [[Around the World in 80 Treasures]]
