Witcher 2 where do I find this extra content?

In The Witcher 2 Enhanced Edition, which playthrough will reveal the content that involves the screenshots below? Screenshots are from the Steam store. I have played Iorveth path and Roche path, before the Enhanced Edition dlc updates and one playthrough on the Roche path after the Enhanced Editon. I am guessing the Radovid screenshots are from the Iorveth path, I just want to make sure. I never saw Radovid with troops marching or on a boat with some kind of sorceress lady with her hands tied up. Maybe this is all in some cut scenes. I also do recall seeing a picture in a magazine of large amount of people in a throne room with what looked like Radovid on the throne anyone know when that happend?

The third picture is from the epilogue of Roche's path. The second isn't a quest I think, just promotional. The first is from Iorveth's, but I'm not sure.
