The Wellcome Trust has released its Wellcome image collection under the Creative Commons Attribution, Non-commercial Licence 2.0. We’ll see how
we can use it in Wikipedia. Here is a short collection of some images of the Wellness category:
Digitally enhanced MRI of the human head showing the brain and spinal cord in orange/yellow and the other tissues in blue and pink.
6 day old human embryo beginning to implant into the lining of the uterus (endometrium).
It’s good to see improvements and projects like this one.
Update: According to the useful comments below, here are some resources (Wikimedia Commons Licensing and freedomdefined.org) saying that we can’t use these in Wikipedia.
