Let's assume the code below

--------------------------------------------------------
use Tk;
use Tk::Canvas;


 my $box = [0, 0, 500, 500];

 my $mw = new MainWindow;


 my $c  = $mw->Scrolled(qw/
          Canvas -bg white
          -xscrollincrement 1
          -yscrollincrement 1
          -confine 0
          -scrollbars se
          -width 500
          -height 500/,
          -scrollregion => $box,
          );
 $c->pack(qw/-fill both -expand 1 -side top/);
----------------------------------------------------



How the Tk::Photo be applied to the above canvas instance?
