You can achieve this by setting an appropriate background image for the window and setting AllowsTransparency to True:

<Window x:Class="WpfApplication1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" WindowStyle="None" AllowsTransparency="True">
    <Window.Background>
        <ImageBrush ImageSource="/bg.png"/>
    </Window.Background>

Then you have to create your own title bar, because the default one will not be displayed.
