//The DockPanel_Button_Click method works because the of the way the XAML was written for the Image control.
//Notice the soure is explicitly set to a BitmapImage.
//
//By writing the application this way, we avoid handling the download ourselves. The below method simply
//extracts information we have already downloaded.
//
//UI XAML:
//
// <Image VerticalAlignment="Top" DockPanel.Dock="Left" Height="90" Width="65" Margin="7" >
// <Image.Source>
// <BitmapImage UriSource="{Binding Path=ImageURL}" />
// </Image.Source>
// </Image>
