I have DotNetNuke Community Edition 5.3.1. I started to create new skin. Everythings so far very well except that my Menu looks ugly. Images are missing.

Basically I have tried to copy the menu logic, stylesheets and Images from standard installation (MinimalExtropy), but it not work out. What I get is menu in plain text based menu. Hyperlinks behind the menu titles are ok. Why images like menu_bg.png and menu_active.png are not diplayed?

What could be wrong?
Actually. Does any body have clean skin package with functioning menu for me?

Index.html
<object id="Object1" codetype="dotnetnuke/server" codebase="NAV">
            <param name="ProviderName" value="DNNMenuNavigationProvider" />
             <param name="IndicateChildren" value="false" />
             <param name="ControlOrientation" value="Horizontal" />
             <param name="CSSControl" value="mainMenu" />
</object>

skin.css
I have added followings: @import url("css/menu.css");

/Images
All menu images copied directly. (for menu_bg.png & example menu_active.png)

css/menu.css
CSS files directly copied from MinimalExtropy of DNN5.3
