Forgot to ->pack() your widget and main window!

    I tried that too, but it gives me 
    wrong # args: should be "pack option arg ?arg ...?" at t.pl line 9.

    when I use ->pack and 
    bad option "image1": must be configure, forget, info, propagate, or sl
+aves at t.pl line 9.

    when i use ->pack(-anchor => 'sw')
    Thanks for your response, anyways.

      To make up for my ignorance:

      #!/usr/bin/perl
use strict;

use Tk;
use Tk::Photo;

my $main = new MainWindow;

my $photo = $main->Photo(-format => 'gif', -file => 't.gif');

my $canvas = $main->Canvas(
    -width => $photo->width,
    -height => $photo->height,
)->pack( -side => 'top' );

$canvas->createImage(0, 0, -image => $photo, -anchor => 'nw');

MainLoop;

      Tk::Photo is not a widget, just an object that contains the photo. Use a Tk::Canvas to display the photo.

        That works, but a Canvas is overkill: 
        #!/usr/bin/perl
use strict;

use Tk;
use Tk::Photo;

my $main = new MainWindow;

my $photo = $main->Photo(-format => 'gif', -file => 't.gif');

$main->Label(-image => $photo)->pack;

MainLoop;

    Oh, the question was, as you undoubtedly guessed, "How do I get it to work". Just posting it here, because I can't edit the root node any more.
