Interesting Q, Ockham. here's mt 2 cents (two cents not being worth what they once were): If you want to think of art as an industry and not as... um... art, then I do believe it is quantified by numbers of images produced. How may bussiness cards, T-shirts, book jackets... that sorta thing. Art for the sake of art however, in my grand summation (take with grain of salt), is beyond quantification. Sure, one could live an entire existence as an artistic expression. I think it trancends numbers... Sorta like a mothers love for her child, can't be quantified.
