I agree that they are thought-provoking when paired with the ridiculous laws. But without that context, they don't seem to be particularly thought-provoking or visually stimulating. For me, that tips me in favor of "no, they're not art". How many times have folks here railed on about how, for example, the title shouldn't matter in the interpretation of the image? Or about how art is like a joke - if you have to explain it, it's no good? "It's all about the image!" I read again and again. Don't these pictures need the explanation (the pairing with the laws) to be fully appreciated? Can they stand on their own? I'm not so sure.
I think one of the greatest ruses that photographers have to by into is the whole "It needs to say something" crap. I couldn't disagree with that more. Yes, photos often do, but that doesn't mean they have to.
As for being paired with the descriptions of the laws, that's only required if you want people to know it's about the laws.
The David Bowie kid? I look at that, on its own, and see how the appreciation of musicians from the past isn't lost. After all, here's a kid painted up like Ziggy Stardust.
The bouncing pickles? Don't even get me started.
Someone who looks at a photo and can't see something is someone completely devoid of imagination...
