Okay, so I'm trying to stick an image in my new lj layout and following this guide. Ignoring the fact that once I did the CSS thing, my colors all changed, I'm at this stage of things:

* Go to "Background":
Background Pattern: none
Background Image: url of banner
Background Image Repeat: Don't Repeat
Background Image Position: Top
Background Image Scroll: Scroll

Am I just fucking blind or did LJ change their customization page after the guide was made? Where the fuck do I do this at?!?!
