Mrs Sutton is psychiatrist who is a specialist on PTSD. When you read her CV, it is impressive. She no longer works for the US Army, she works for the City of New York.
When you read the article on Wikipedia, you find her picture. It is marked as Public Domain and it is not on Commons. Given that Wikidata is working towards the point where copyright and license information one can only hope that images like this can be easily shared based on the license.
When Commons started, it was intended as a repository that prevented the same file to be uploaded to all the Wikipedias. As such it served its purpose remarkably well. With Wikidata it becomes trivial to share images like the one of Mrs Sutton.
I fear that for some this reads as frightening. It undermines the one thing they love. It actually does not need remove the need for Commons as a platform. Quite the opposite; it will bring new tools to finally leverage all the data on images. It may bring this image of Mrs Sutton to Wikidata for starters.
