Using a background image in the Page Background

[Warlord]

In the Admin CP under the Style Manager -- Skin you want to edit --> Main CSS, I'm trying to use an image for the Page Background.

I added the following CSS to the Extra CSS Attributes but haven't noticed any changes.

{
background-image: url('http://www.projectfanboy.com/vb/images/skins/superman_bg.jpg');
background-attachment:
fixed
}

Is there something wrong with my code?

That is not valid CSS. You have opening and closing brackets, but you do not specify any tags to apply it to. You are most likely looking for this:
body {
background-image: url('http://www.projectfanboy.com/vb/images/skins/superman_bg.jpg');
background-attachment: fixed;
}

Actually I was just inserting the code in the little box next to the Standard CSS Attributes under Page Background but that didn't work either. :(

Then I noticed that the css selector was called .page so I tried adding the following code to the Additional CSS Options all the way at the bottom of the screen but it didn't work either.

.page
{
background-image: url('http://www.projectfanboy.com/vb/images/skins/superman_bg.jpg');
background-attachment:
fixed;
}

What am I doing wrong?

Your URL is invalid. Therefore, no image will be displayed.
Try it like this.
.page
{
background-image: url('http://www.projectfanboy.com/images/skins/superman_bg.jpg');
background-attachment:
fixed;
}

Wow, I'm an idiot. LOL, Thanks. :)
