WPF Xaml Image from Converter

i cant bind an image to source from converter?

<!-- Works fine -->
<Image Grid.Row="0" Grid.Column="4" Grid.RowSpan="6" Margin="5">     
      <Image.Source>
          C:\pictures\Becker.png
      </Image.Source>
</Image>


<!-- Works not -->
<Image Source="{Binding ClientPicture, Converter={StaticResource clientpictureconv}, ConverterParameter={Binding ClientNumber}}"/>

In the converter i give back the hardcoded picture Uri (from the top). If i replace the Image with Textblock, the full uri is shown. But the picture in Image not.

What can i do?

That's because Image.Source does not take a URI object; it takes an ImageSource object. Your converter should create one of those and pass it back. Put this in your converter, and it'll work:

return new BitmapImage(myUri);

Note that BitmapImage is a type of ImageSource.

Your first example works because XAML implicitly converts the URI string to an ImageSource for you. It can't do that when you explicitly pass back a URI object using your converter.
