I guess the big question is. if photos can be art and murals can be art, are photos of murals art or just photos of art? if they are just photos of art then the artist deserves reconition for the work they created. if they to are art, they would fit into the goup of a colaboration i would think and if so wouldnt it be propper to give credit to the artist you did the colorabation with? im not saying you should be punished by law for it. :O i was just trying to give constructive critisim. 8D
