WPF Image绑定一个枚举，希望在枚举值改变时显示不同图片。该如何解决

<Image Name="img"  Height="26" Margin="2" Source="1.png" 
               DataContext="{Binding Path=.}">
          <Image.Triggers>
            <DataTrigger Binding="{Binding Path=CurrentStatus}" Value="Connect">
              <Setter Property="Source" TargetName="img" Value="2.png" />
            </DataTrigger>
          </Image.Triggers>
        </Image>

  public enum AvailableStatus {
    Connect,
    DisConnect,
  }
