Hintergrundbild fest positionieren

[Prinz]

Hallo zusammen,

ich habe folgende Seite neu erstellt. www.feuerwehr-schmergow.de

Wenn ich die Seite im Browser in der maximierten Ansicht anschaue passt alles. Wenn ich jetzt aber das Browserfenster verkleinere und nach links schiebe, schiebt sich auch das Hintergrundbild aus dem Inhaltsbereich nach links.

Wie kann ich das verhindern?
Hier meine CSS

``

body
{
 margin-top: 0px;
 margin-left: 0px;
 margin-right: 0px;
 margin-bottom: 0px;
 background-color: #000;
 padding:0px;
 background-image:url(../images/bg.gif);
 position: static;
}

td {
font-family: arial, helvetica, tahoma ,verdana,  sans-serif;
text-align:justify;font-size: 94%;line-height: 125%;}

h2{
 color:#FFFFFF;
 margin-bottom:20px;
