I would like to use ToggleButton in following way: There are 5 different images and each of them should be displayed depending on current state:

1. button disabled
2. button enabled, unchecked
3. button enabled, unchecked, pointed by mouse cursor
4. button enabled, checked
5. button enabled, checked, pointed by mouse cursor

I've found a simple example with two images on http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/28c36bd2-2ef7-4232-9976-2a0967140e32 , but how to change the image depending on "checked" property?

The second question: how can I avoid creating different styles for each button in my application? I'm using about 20 different buttons and each of them has different set of icons.

So far I'm using only one icon, below my code. Is it possible to have common code (style and template) and to define the source of images in section where I want to create button (like in section 3 of my code)?

<ControlTemplate x:Key="ToggleButtonTemplate" TargetType="{x:Type ToggleButton}">
    <Grid>
        <Border x:Name="ContentBorder" CornerRadius="4" BorderBrush="Transparent" BorderThickness="1" Background="{DynamicResource ButtonOff}">
            <ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" RecognizesAccessKey="True"/>
        </Border>
    </Grid>
    <ControlTemplate.Triggers>
        <Trigger Property="IsPressed" Value="true">
            <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonOn}"/>
        </Trigger>
        <Trigger Property="IsChecked" Value="true">
            <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonOn}"/>
        </Trigger>
        <Trigger Property="IsEnabled" Value="false">
            <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonDisabled}"/>
            <Setter Property="Foreground" Value="{DynamicResource BorderDisabled}"/>
        </Trigger>
    </ControlTemplate.Triggers>
</ControlTemplate>

<Style x:Key="ToggleButtonStyle" TargetType="{x:Type ToggleButton}">
    <Setter Property="Width" Value="64" />
    <Setter Property="Height" Value="64" />
    <Setter Property="HorizontalContentAlignment" Value="Center"/>
    <Setter Property="VerticalContentAlignment" Value="Center"/>
    <Setter Property="Template" Value="{DynamicResource ToggleButtonTemplate}" />
</Style>

<ToggleButton IsChecked="{Binding Path=IsLectorModeEnabled}" Command="{Binding CmdLector}" Style="{DynamicResource ToggleButtonStyle}">
    <Image Source="{DynamicResource LectorImage}" HorizontalAlignment="Center" VerticalAlignment="Center" Stretch="None" />
</ToggleButton>
