Ignoring the question of the ethics of the original place the image was published, which is a long and many sided discussion that no one is going to “win” any time soon, there is a second issue: the ethics of using an unlicensed image. This may also be a grey area (some arguing “information wants to be free” overrides such matters), but legally the “ethics” are far more black and white.

Though I think these comments are getting far too bogged down on the ethics and legality of using the Lena image, and ignoring the fact that Morten's new image & related post is (at least mainly) intended as a bit of fun, poking at just these sorts of discussions.
