Picture credits

Deutsch

The cover pictures of the free tours come from Wikipedia and Wikimedia Commons. They carry free licences that allow reuse — but not anonymously: the author and the licence have to be named. That is what this page is for.

We store the pictures on our own server rather than hotlinking them from Wikimedia. That spares their bandwidth and keeps the gallery working when somebody else's server does not.
