Non-free use for [[Lenna]]

The image is used in the context of that article to illustrate the subject of that article. The image linked here is claimed to be used under fair use as:

  1. It is a historically significant photo
  2. This 512x512 scan of a small portion of the original image is of much lower resolution than the Playboy original, and differs greatly in color balance and contrast due to the scanner technology and calibration at the time (copies made from it will be of very inferior quality).
  3. The photo is only being used for informational purposes
  4. Its inclusion in the article adds significantly to the article because it shows the subject of this article

Also see the Jan 2007 discussion which resulted in a consensus that this and other standard test images do not violate Wikipedia's Fair Use policy, and the 2011 FFD discussion.
