Answer 1

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

Replace your TextBlock

with an Image and tell it use your converter
