WPF TabItem - Image Binding - using Triggers - wpf

Question

I want to show Image inside of the Title of header in TabControl
This question(WPF TabItem - Image Binding) seems is right, but I have using Triggers and it doesn't help on my code.
Here is what I have Providing:
<TabControl Name="MainTabControl" Margin="0,28,0,0" TabStripPlacement="Top" >
<TabControl.Resources>
<Image x:Key="imgProfile" Source="/Icons/red icons/profile.png" />
<Image x:Key="imgComment" Source="Icons/red icons/notification.png" />
<Style TargetType="TabItem" >
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate>
<WrapPanel>
<TextBlock Text="{Binding}"
MouseDown="UIElement_OnMouseDown"
FontSize="18"
/>
<Image Height="25" Margin="4,0,4,0"
Source="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=Tag.Source}" />
</WrapPanel>
</DataTemplate>
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabItem">
<Border Name="Border" BorderThickness="1,1,1,0" BorderBrush="Gainsboro" CornerRadius="0" Margin="2,0">
<ContentPresenter x:Name="ContentSite"
VerticalAlignment="Center"
HorizontalAlignment="Center"
ContentSource="Header"
Margin="5,2"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="False">
<Setter TargetName="Border" Property="BorderBrush" Value="Transparent" />
<Setter TargetName="Border" Property="Background" Value="Transparent" />
<Setter Property="Foreground" Value="{DynamicResource TabItemNormal}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</TabControl.Resources>
<TabItem Name="tiProfile" Header="a" Tag="{StaticResource imgProfile}"></TabItem>
<TabItem Name="tiComment" Header="b" Tag="{StaticResource imgComment}"></TabItem>
</TabControl>

Answer 1

the binding from TabItem.HeaderTemplate to the TabItem.Tag must be via FindAncestor of TabItem type.
instead create Images in Resources, create BitmapImage, and bind it the Image.Source.
so, Resources:
<BitmapImage x:Key="imgProfile" Source="/Icons/red icons/profile.png" />
<BitmapImage x:Key="imgComment" Source="Icons/red icons/notification.png" />
Header DataTemplate:
<Image Height="25" Margin="4,0,4,0"
Source="{Binding Tag, Mode=OneWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type TabItem}}}" />
