Error in Icon Image of Context Menu

I m getting error after running the application "error:Sys.InvalidOperationException: ImageError error #4001 in control 'ctl00_ContentPlaceHolder1_Xaml': AG_E_NETWORK_ERROR" in below code

            <toolkit:MenuItem Header="Accoustics">
            <toolkit:MenuItem.Icon>
                    <Image x:Name="menuIcon1" Source="Images//Arrow.PNG" Height="30" Width="30" Stretch="Fill"/>
                </toolkit:MenuItem.Icon>
            </toolkit:MenuItem>
            </toolkit:ContextMenu>

strange thin开发者_开发技巧g is that i m able to see image in design view.

any idea??

Thanks. -Nitin

Is correct the path Source="Images//Arrow.PNG"? Try the correct path Source="Images/Arrow.PNG"
