Background picture in Green Shoes

Question

I have a very simple question. On the Green Shoes website one can read that it is possible to set a image as the background of a app (cf. http://ashbb.github.io/green_shoes/Background.html). However I have tried it but it does not seem to work.

background black  #Works

image "my_pict.jpg"  #Works

background "my_pict.jpg"  #Does not work

Thanks in advance!

Do this

background url(/path/to/image/my_pict.jpg);
