You can't attach a Photo to a MainWindow (Correction: Yes, you can, see Jouke's great example "below"). It needs to belong to a Label or a Button or a Text widget (and probably others).

my $mw = MainWindow->new;
my $button = $mw->Button()->pack();
my $photo = $button->Photo( -format => 'jpeg', -file => 'test.jpg' );
$button->configure( -image => $photo );
MainLoop;

See also the perldoc for Tk::Photo, it's infinitely more useful than the docs for Tk::JPEG.

Update: now tested, added configure method, without which Tk never realizes it's supposed to be the -image for $button.
