There are several ways to achieve this, but perhaps the simplest way is to use the Navigate method.

When the user clicks on your first image, grab the "id" of that image (or url, or whatever you need to pass to the second page), and add it to the navigation string like this:

NavigationService.Navigate(
  new Uri(string.Format("/MyNewPage.xaml?image={0}",myImageID), UriKind.Relative));

Then on the destination page, you can extract that item from the navigation string in the OnNavigatedTo handler:

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
    myImageID = int.Parse(NavigationContext.QueryString["imageID"]);
}

Like I say, this is a very simplistic approach, and you can implement something much nicer with databinding, but it will do the trick.
