Answer 1

You should use Binding with value converter: http://blogs.msdn.com/bencon/archive/2006/05/10/594886.aspx

Answer 2

Create a Value Converter

It takes your enum value and returns the filename of the appropriate icon.

[ValueConversion(typeof(AcceptationStatusGlobalFlag), typeof(string))]
public class AcceptationStatusGlobalFlagToIconFilenameConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        switch ((AcceptationStatusGlobalFlag)value)
        {
            case AcceptationStatusGlobalFlag.Ready:
                return "ready.jpg";
            case AcceptationStatusGlobalFlag.NotReady:
                return "notready.jpg";
            case AcceptationStatusGlobalFlag.AcceptedByAdmin:
                return "AcceptedByAdmin.jpg";
            default:
                return null;
        }

        // or
        return Enum.GetName(typeof(AcceptationStatusGlobalFlag), value) + ".jpg";
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotSupportedException();
    }
}

You will need to add a reference to this converter in your XAML

<Window ... xmlns:converters="clr-namespace:App.Converters" ...>
    <Window.Resources>
        <converters:AcceptationStatusGlobalFlagToIconFilenameConverter x:Key="IconConverter"/>
    </Window.Resources>

Replace your TextBlock

<TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text="{Binding Path=AcceptationStatusGlobalFlag}" />

with an Image and tell it use your converter

<Image Source="{Binding AcceptationStatusGlobalFlag, Converter={StaticResource IconConverter}}"/>

Answer 3

The most easy solution to this, is to use a value convertor; so create an IValueConverter implementation that converts your enums to the corresponding images.
