Effectiveness of a release statement?

[berlinlife06]

I think that should "cover" you, but you have to see if the pictures and quotes you use from other people, specifically say that it is copyright protected, or if they also say something like: the use of any material requires the written permission of the owner. That, as far as a I know, is like a double protection authors use, so they can sue whoever didn´t ask for permission... I would be careful with that!
