You can put pictures behind it but I instead used the same background I have in ehome and it looks like it is part of the system. It also takes any RSS/html/text feeds and so I have it showing my favourite news stories.

I have no connection to this company and so don't know how well this is supported but this definitely got my wife's approval. Something the touch screen didn't get when I first installed it
