I think it's a little strange to call a method on $button before you have declared $button with my $button. Maybe you patched your parser with a lookahead feature, "hey, do I declare this later, if so I can use it now, right?" :)

    Brrr...you're right! I was way too quick with my answer! It should be this: 
        my $mw = MainWindow->new;
    my $photo = $mw->Photo( "photo"
                            -format => 'jpeg', 
                            -file   => 'test.jpg' );
    my $button = $mw->Button(-image => "photo")->pack();
    MainLoop;

      Now that's a trick worth knowing about! Keeping all image widgets as children of the MainWindow rather than in the widgets themselves makes managing them a lot easier (flipping images in Tk is a terrible memory leak unless done very carefully). It also allows for sharing a single photo widget among several other widgets if needed without having to reparent the original photo each time.

      Hi looking for something like this just to give me an idea I notice a missing comma it should be like this ? 
      my $mw = MainWindow->new;
    my $photo = $mw->Photo( "photo",
                            -format => 'jpeg', 
                            -file   => 'test.jpg' );
    my $button = $mw->Button(-image => "photo")->pack();
    MainLoop;
