Web picture match?

Does anybody know if there exists a service (I think it should be possible at least) which by computer computation can match an image, and find similar ones on the web? Say, if I want to know who painted the painting behind the gentleman here?



It's photographed off my TV, and the gentleman is an art expert, formerly with the MOMA in NYC.
He, by the way, is one of the most beautifully arrogant people I've ever seen. He totally and offhandedly dismisses the opinion of anybody who does not have his own expertise. He even dismisses the evidence of fingerprints, saying that his own feeling of a painting overrides that. Great stuff.

It's from an documentary, Who The F..k is Jackson Pollock. It's delightful, full of quirky characters from real life.
