<style>body{background-image:url("PUT YOUR OWN URL HERE");}<style>
If you want a url and you dont know how to get one, upload a picture to tinypic or photobucket, it doesnt matter much. I usually use tinypic so i would suggest that right now. Then copy the code that says "direct link to layouts" and paste it where I put "put your own url here"
See, that was easy
