Hi,

It took me a while, but I found a way to do what you asked for.  The trick is to set the LabelPresenter's ContentTemplate to a DataTemplate that shows both the Image and the header text.  Here's an example:

<igDP:FieldLayout>
<igDP:FieldLayout.Fields>
<igDP:Field Name="name">
  <igDP:Field.Settings>
    <igDP:FieldSettings>
      <igDP:FieldSettings.LabelPresenterStyle>
        <Style TargetType="{x:Type igDP:LabelPresenter}">
          <Setter Property="ContentTemplate">
            <Setter.Value>
              <DataTemplate>
                <DockPanel>
                  <Image
                    DockPanel.Dock="Left"
                    Source="icon.png"
                    Margin="2,0,4,0"
                    PreviewMouseDown="Image_PreviewMouseDown"
                    Width="15" Height="15" 
                    >
                    <!--
                    Scale up the image render size because
                    the default layout slot is not too big.
                    -->
                    <Image.RenderTransform>
                      <ScaleTransform
                        CenterX="7" CenterY="7"
                        ScaleX="1.4" ScaleY="1.4"
                        />
                    </Image.RenderTransform>
                  </Image>
                  <ContentPresenter
                    ContentTemplate="{TemplateBinding Content}"
                    HorizontalAlignment="{TemplateBinding HorizontalAlignment}"
                    VerticalAlignment="{TemplateBinding VerticalAlignment}"
                    />
                </DockPanel>
              </DataTemplate>
            </Setter.Value>
          </Setter>                           
        </Style>
      </igDP:FieldSettings.LabelPresenterStyle>
    </igDP:FieldSettings>
  </igDP:Field.Settings>
</igDP:Field>

...In the code-behind...

void Image_PreviewMouseDown(object sender, MouseButtonEventArgs e)
{
    // Handle the event so that the field header does not get clicked.
    e.Handled = true;

    Debug.WriteLine("You clicked the icon!");
}

You don't need to do that from code.  I showed how to do something similar here.
