Err... mrhakumei, I don't really understand what you're trying to tell him to do, but here's an easier way that doesn't require using your Web Browser:

Press Print Screen|SysRq (top-right of the keyboard), and then open up MS Paint. Should be in Start Menu > All Programs > Accessories > Paint. Ctrl + V your screenshot into the Paint window, and then save the picture as a .gif or .jpg or whatever suits your needs.
