Add large background-image to Subsonic login page

[mockingbrd]

I would like to use a large image as the background of my login page, ala Bing, Twitter etc. Would someone be able to help me out? I'm not sure what file to look-in to edit the HTML, or the HTML code to add a large background-image (I could probably just google that). Any info would be appreciated, thanks!
