To complement Kenneth's answer, here's how you'd do it in C#;
string url = @"http://maps.googleapis.com/maps/api/staticmap?center=Berkeley,CA&zoom=14&size=400x400&sensor=false";
BitmapImage bmpImage = new BitmapImage();
bmpImage.BeginInit();
bmpImage.UriSource = new Uri(mapURL);
bmpImage.EndInit();
MapImage.Source = bmpImage;
