main background fixed?

How fixed I my main background, I think I overlook here something but can't get it...
I want the background stay's and scroll the pages.

Someone give a hint please?

In template/tmpl_uni/css/general.css for the background of the body it would look like this:

 body
 {
  width: auto;
  min-width: 960px;
  margin:0px;
  padding:0px;
  background:url('../images/your-image-here') fixed; /*sorry corrected, this is the basic setting*/
  font-family:Arial;
  font-size:11px;
  color:#ffffff;
   
 }

This does not effect members uploaded pics in their profile. To do that you would have to copy this same style to the "profile_view.css" in that same directory.

In templates/tmpl_uni/css/main.css just add the following line inside your tag body:

background-attachment:fixed;

Thanks Guys.... I was overlooked it .
