Two blogs ago, Jurgen wondered about how copyright is handeled when you take a picture from a picture.
So, I consulted my former media law teacher Piet Martens at the Arteveldehogeschool in Ghent. His explanation: It is the journalistic right to quote (“journalistiek citaatrecht”): You can reproduce a piece of expressive art completely or partly when you report about news facts, on the condition that you provide the source and author.
So, as I mention the photographer and the exhibition in order to draw your attention to the photographer, I see no problem. It is like announcing the newest photobook of Vanfleteren and showing an image of the exhibition. It stays a thin line, though.
