Crash on changing the Image source property

Question

<Image x:Name="pageImg" Margin="-19,-1,37,19" Source="/img/1.png" Stretch="Uniform"  />

The images property also set to Build Action = Resource and Copy Output Directory = Cope if newer

When the button get clicked the application crashes:

    private void Button_Click_1(object sender, RoutedEventArgs e)
    {
            pageImg.Source = new BitmapImage(new Uri(@"/img/2.png"));
        }

But when I pass C:\Users\myuser\Desktop\2.png instead of /img/2.png it works just fine.

Why this is happening?

An image resource file (with Build Action set to Resource) should be loaded by a Resource File Pack URI:

pageImg.Source = new BitmapImage(new Uri("pack://application:,,,/img/2.png"));

It is not necessary to get it copied to the output directory.

This solved my problem :

pageImg.Source = new BitmapImage(new Uri(@"/img/2.png", UriKind.Relative));
