Title • (re)presenting graffiti

Tobias made an interesting point yesterday, when he commented on my entry:

"I mean a Banksy image (www.banksy.co.uk) is considered art but you wouldn’t post it as a photograph on your site because that would be considered plagerism"

And I assume that this can be applied more generally: graffiti is art, therefore its reproduction is a form of plagiarism – claiming somebody else's work as your own. Now, and this is an issue that's been raised before on chromasia, clearly I don't hold this view – if I did I wouldn't post this sort of stuff – but I thought it was probably something that we could discuss. Is it theft/plagiarism, is it simply a form of documentation, is it something else? I'll write more about my own views – either in the comments or on tomorrow's entry (another graffiti shot) – but I'd be grateful if you could let me know what you think.
