we always set picture to desktop.It is boring to me. I don't know your idea about that. But try this. Not a big thing. Small html code. every thing is basic. No need of deep knowledge in html. After setting this web page. you can view website without using a browser. Think you can watch your facebook just press show desktop button or super+p. Here i use google to demonstrate it this. You can change your preferred website in to code which i given below. Here is the code.
<body>
<iframe src ="http://www.google.com" width = "100%" height="100%">
</iframe>
</body>
</html>
type this in notepad and save it as "anyname.html" and select this website as your desktop background. After setting you will see your lovely desktop like this...
