> Lena is no longer used as a test image because it's porn.

The Lenna test image can be seen over the text "Click above for the original as a TIFF image." at [0]. If you consider that to be porn, then I find your opinion on what is and is not porn to be worthless.

The test image is a cropped portion of porn, but if a safe-for-work image would be porn but for what you can't see in the image, then any picture of any human ever is porn as we're all nude under our clothes.

For additional commentary (published in 1996) on the history and controversy about the image, see [1].
