And to your question as to how to make them that way, you can get any image software, photoshop or gimp, paint might even let you reize and you basically just punch in the numbers you want. Be careful though it may stretch a picture and make it look funny. Which is why I use photoshop or gimp. You make a "new image" of the size you want. Then take your pic you want and make it a new layer with in your project. then you make the image bigger or smaller, you'll loose either off the top/bottom or the left/right side if your going from widescreen to non widescreen or the other way around.
