How do I take picutures of weapons?

Im new to this site and I was wondering how people get all those pictures of their weapons and armor up. Is there some kind of special program that you have to use or can you do it while playing?

You just sreenshot it by pressing "Print Screen" on your keyboard.
it should save it in the screenshot sub-folder in the GW folder.
open the image in photoshop or something and cut out whats not needed.

k thanks

Shift + Printscreen removes your GUI from the screenshot too.

...and if you want to take good looking pictures, read the hints here:
