WPF mouse button image

I am learning C # and XAML for building Windows applications. I wanted to create a button with an image as a background. But when you hover over the button, the background of the button should change to another "highlighted" image. I tried adding background images to Resource.resx. I had to create a custom button using xaml styles to get rid of the effect of highlighting the default wpf button.

I created a custom button from some code that I found on SO. Code (in the new resource dictionary):

    <!-- This style is used for buttons, to remove the WPF default 'animated' mouse over effect -->
    <Style x:Key="StartMenuButtons" TargetType="Button">
        <Setter Property="OverridesDefaultStyle" Value="True"/>
        <Setter Property="Margin" Value="5"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border Name="border" 
                        BorderThickness="0" 
                        Background="{TemplateBinding Background}">
                        <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">


                        <!-- UPDATE THE BUTTON BACKGROUND -->
                        <Setter Property="Background" Value="WHAT GOES HERE"  TargetName="border"/>


                    </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
