Nice and fast Noté 5 sur 5 étoiles

1. It doesn't proceed Wikipedia. Other sites it proceeds
2. Is it possible to add custom background (some local image or even folder with images to choose randomly)?
I mean background outside the frame (not for the text). It would be nice
3. Some sites are organized so, that their left and right sides are empty or not interesting. In such cases the user will prefere background even without text proceeding, i.e. only to cover these boring sides. Is it possible?
Thank you.
