display image in silverlight 4

  MyImage.Source = new BitmapImage(new Uri("../Image/" + txtImage.Text,
                                   UriKind.Relative));

Why is the image not showing?

Your relative URI cannot contain and especially start with "../".

Unless it starts with a "/", or an absolute URL starting with "http://", it is assumed to be in a module.

A URL like "/images/imagename.jpg" will find the image located in the clientbin/images folder on the hosting website.
