Well, you know, the show showed some restraint. After all, they could have used these photos.... Just kidding. These are of the actors, not the characters, on their recent tour to promote the show in Europe (i.e Adrian Pasdar, Jack Coleman, Milo Ventimiglia and Hayden Panettiere went to Europe, the rest of the cast did Asia and the US; in short, we got the Petrelli/Bennet team!). There is a fun (and unspoilery, don't worry) picspam of that tour
here.
