Urgh, I've never had any trouble with it. What's the background URL?
EDIT: It may be your template. I don't think I've ever seen a blog here that uses that template and has a a background. You could try using a different template (there are two others)?
I could use html and manually put it in eaither by the tags [img] [/im] or <img src" "> But guess what? Niether work, lol.
Should I delete the blog and put in the url instead of picking a boring template?
*bangs head against the wall* Comps give me such a headache sometimes!
