Keeping in mind that I am not a lawyer and corrections/additions to what's below are very welcome . . .

The license for the excellent (even if not quite "family-rated") Pixl test image reads like many/most test image licenses. The image can't be redistributed as part of a package of test images. Nor can it be used commercially.

Which raises the question of how to license a package of test images, hopefully in a way to be compatible with distribution alongside free/libre software.

CC-BY-SA (used by Wikipedia and compatible with free software) allows commercial use of images. AFAIK commercial use does require a release from all recognizable people in the image.

Releasing an image as public domain/CC0 (also used by Wikipedia and compatible with free software) requires consent of the person taking the photograph and also would seem to require the consent of any recognizable person being photographed.

Also, if there is a recognizable person in the image, the thorny issue of personality rights is raised (

So two practical questions are how to license and how to distribute the test images.
