c# - RadioButton and image

Question

I try to set up images instead of bullet for my RadioButtons. I've 10 RadioButtons but I can't setup my FishImg for all. Only the rb I clicked just before displays the imgFish.

My Style

    <Style TargetType="RadioButton">
    <Setter Property="Content" Value="{DynamicResource imgFish}"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type RadioButton}">
                <Grid>
                    <Image Source="Images/empty.png" Width="24" Height="24" />
                    <ContentPresenter/>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
    <Style.Triggers>
        <Trigger Property="IsChecked" Value="True">
            <Setter Property="Content" Value="{DynamicResource imgHero}"/>
        </Trigger>
        <Trigger Property="IsChecked" Value="False">
            <Setter Property="Content" Value="{DynamicResource imgFish}"/>
        </Trigger>
    </Style.Triggers>
</Style>

My XAML

                <RadioButton Grid.Column="2" Grid.Row="1" Name="hvP1" />
                <RadioButton Grid.Column="2" Grid.Row="2" Name="hvP2" />
                <RadioButton Grid.Column="2" Grid.Row="3" Name="hvP3" />
                <RadioButton Grid.Column="2" Grid.Row="4" Name="hvP4" />
                <RadioButton Grid.Column="2" Grid.Row="5" Name="hvP5" />
                <RadioButton Grid.Column="2" Grid.Row="6" Name="hvP6" />
                <RadioButton Grid.Column="2" Grid.Row="7" Name="hvP7" />
                <RadioButton Grid.Column="2" Grid.Row="8" Name="hvP8" />
                <RadioButton Grid.Column="2" Grid.Row="9" Name="hvP9" />
                <RadioButton Grid.Column="2" Grid.Row="10" Name="hvP10" />

Finally I found it today even if I was pretty sure I tried it yesterday... may be tired.

Here a working solution
