// Open a Uri and decode a GIF image
Uri myUri = new Uri("tulipfarm.gif", UriKind.RelativeOrAbsolute);
GifBitmapDecoder decoder2 = new GifBitmapDecoder(myUri, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
BitmapSource bitmapSource2 = decoder2.Frames[0];

// Draw the Image
Image myImage2 = new Image();
myImage2.Source = bitmapSource2;
myImage2.Stretch = Stretch.None;
myImage2.Margin = new Thickness(20);
