I would like to change the background on my website http://www.tunermaneuvermag.com to a custom wallpaper/background image I made. I would also like to change the background area where the posts are the homepage are to a custom background/wallpaper. How do I got about doing so? I would like it to be setup similar to this website http://www.greasyblocks.com . I need to know what image files or what I need to code in override.
Any help would be awesome.
