Picture credits

Bildnachweis

Aventa tours are illustrated with photographs from Wikimedia Commons, published by their authors under Creative Commons licences. Those licences allow commercial use, and they ask for one thing in return: that the author is named, that the licence is named and linked, and that any change to the picture is stated. This page does that for every such picture in the catalogue.

Most stop pictures are painted over as watercolours, and most game tiles are crops — both count as changes, so each row says so. Where a picture is licensed CC BY-SA, that adapted picture stays under CC BY-SA; this affects the picture alone, not the tour text, the audio or the app. A picture that carries no credit here is our own photograph or was generated with AI; where a tour is still being traced back to its sources, its section says so.

Deutsch: Viele Bilder in unseren Touren stammen von Wikimedia Commons und stehen unter Creative-Commons-Lizenzen. Diese Seite nennt zu jedem Bild den Urheber, die Lizenz und die vorgenommene Änderung. Bearbeitete CC-BY-SA-Bilder bleiben unter CC BY-SA; das gilt nur für das Bild, nicht für Text, Audio oder App. Nicht aufgeführte Bilder sind eigene Fotos oder KI-Bilder; wo die Herkunft noch geprüft wird, steht es im jeweiligen Abschnitt.
