KNOPPIX REMASTERING FOR TWO REG. LANGUAGE.wallpaper trouble

hi friends

I have made a working live cd version of Knoppix IN HINDI.
Hindi localisation in knoppix in actively workin.
By default knoppix takes english version thus to provide hindi, Cheat codes with Knoppix lang=hi is provided.
This redirects me to the desktop with wallpaper which i have created particularly for hi language(i have changed the default settings ).
However if i want to add new locales into it.. say lang=pun (thats for another regional language )
Is it possible to redirect it to some other wallpaper by default???

For changing the background image we have to make changes to the image knoppix.jpg in /usr/local/lib/knoppix.jpg.The image should be of same size and same name.
but only one background image is possible even for various cheat codes.is it possible to redirect to different images when different cheat codes are entered?

i.e if i go for hi it will show another wallpaper background
and if i go for Pun it will show another wallpaper bakground.
Is it possible?? If yes than how ?

thanks in advance
