I'm sure you can find css savvy users on polru.
Generate a base64 code from the Ingria flag, then to custom.css  add something like:


img[title="Russia"]{
    background: url(data:image/png;base64,blahlbah);
}


Still BO is needed to add it to the board.
I think lotsa users have dollchan, I'm not sure what that changes in this regard, and if they need their own custom code. Also no magrathea support yet.
