A user can design a question layout (for an elearning web page) and the 
layout can include an image - the user selects the image from their 
local file system. There's a 'preview' button which opens a new window 
showing the the user the layout.

I've started working with FileReader but I have some trouble getting 
things working. I need help with:

- How can I pass the reader result to the new window?

- How can the reader result be used as a CSS background image?
For an img I can do img.src = reader.result but for a background image 
is it just
div.style.backgroundImage = "url('" + reader.result + "')";
?
