According to Clemens suggestion, here is the binding converter to have a good code-reuse:

namespace Controls
{
    [ValueConversion(typeof(String), typeof(ImageSource))]
    public class StringToImageSourceConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            if (!(value is string valueString))
            {
                return null;
            }
            try
            {
                ImageSource image = BitmapFrame.Create(new Uri(valueString), BitmapCreateOptions.IgnoreImageCache, BitmapCacheOption.OnLoad);
                return image;
            }
            catch { return null; }
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }
}

And there is a string for binding, for example

public string MyImageString { get; set; } = @"C:\test.jpg"

And in the UI the converter is used, in my case from the Library named "Controls"
