Each time I have the need for an image converter for a WPF application, I end up searching the web looking for a sample, so this time, I’m putting a sample somewhere I can find it again easily.  Below is a basic IValueConverter implementation to convert a file name into a BitmapImage located in an images folder.

Code for Sample Project

public class IconImageConverter : IValueConverter
{
    public object Convert(object value, 
                       Type targetType, 
                       object parameter, 
                       System.Globalization.CultureInfo culture)
   {
      // if value isn't null, we can safely do the conversion. 
      if (value != null)
      {
          string imageName = value.ToString();
          Uri uri = new Uri(String.Format("/Images/{0}", imageName), 
                                UriKind.Relative);
          return new BitmapImage(uri);
      }
      return null;
   }
    public object ConvertBack(object value, 
                         Type targetType, 
                         object parameter, 
                         System.Globalization.CultureInfo culture)
    {
       throw new NotImplementedException();
    }
}
