Vista - Re: Problems with Switching Images in XAML

Can't put a URI directly into Image.Source (at least not in code). There's an
intermediate practical ImageSource you have to use as well as a URI ctor.
Have to use something like:

CurrentImage.Source=new System.Windows.Media.Imaging.BitmapImage(new
Uri("file://c:\\msdn_masthead_ltr.gif"));
