Italy knows as well the concept of "diritto all'immagine" but, in fact, its actual field of application is much more restricted than a superficial reading of the norm would induce to think.
After the enunciation of the basic right in principle, which is probably just like in Germany, the law or different laws state a great amount of exceptions:
dispone, che si possa prescindere dal consenso, nei casi in cui ci˛ sia giustificato da motivi di, notorietÓ del personaggio ritratto, o dall' ufficio pubblico ricoperto, o dalla necessitÓ di, giustizia, polizia, scopi scientifici, didattici, culturali, o quando la riproduzione sia collegata a fatti o avvenimenti, cerimonia di interesse pubblico o svoltosi in pubblico
the consent is not required when [publication] is justified by reasons of notoriety of the person portrayed, the public office he holds, necessity of justice /police, scientific-didactic-cultural purposes or when reproduction is linked to facts or events, or ceremonies, of public interest or held in public.
That practically paves the way to every sort of publication. You can publish the pictures shown in this thread, if they are a way to show let's say the apparel of the time.
If there wasn't such a list of exceptions in Germany we wouldn't see all the war documentaries or all kind of documentaries where people is portrayed sometimes as close-up. Journalism and especially documentarism would be basically impossible. I believe Germany should not be different from the rest of the world under this respect.
