   <Image.Source>
      <BitmapImage UriSource="sampleImages/bananas.jpg" />

      <BitmapImage UriSource="sampleImages/bananas.jpg" />
   </Image.Source>
</Image>

// Create the image element.
Image simpleImage = new Image();    
simpleImage.Width = 200;
simpleImage.Margin = new Thickness(5);

// Create source.
BitmapImage bi = new BitmapImage();
// BitmapImage.UriSource must be in a BeginInit/EndInit block.
bi.BeginInit();
bi.UriSource = new Uri(@"/sampleImages/cherries_larger.jpg",UriKind.RelativeOrAbsolute);
bi.EndInit();
// Set the image source.
simpleImage.Source = bi;

' Create the image element.
Dim simpleImage As New Image()
simpleImage.Width = 200
simpleImage.Margin = New Thickness(5)

' Create source.
Dim bi As New BitmapImage()
' BitmapImage.UriSource must be in a BeginInit/EndInit block.
bi.BeginInit()
bi.UriSource = New Uri("/sampleImages/cherries_larger.jpg", UriKind.RelativeOrAbsolute)
bi.EndInit()
' Set the image source.
