Wikipedia, yawn
This is all old news for us Wikipedians. We have created a special website for images, called the Wikimedia Commons. Only free-licensed and out-of-copyright images are permitted. "Don't know" is likely to be taken down for the well-worn legal reasons just discovered by the school.
There is also a "fair use" rationale for some copyright images in certain circumstances, and those can - with care - be uploaded to Wikipedia itself.
I suppose the big news is that even though the EU legal advocate missed the plot, the judgement didn't.
