Hello

I want to use the open_icon_library free icon to build my TK gui. So far I've used png images with the following

my $img = $mw->Photo( -file => 'image.png');
my $button = $frame->Button(-image => $img,
                        -command => \&open,
                        -background=> 'white',
                        -borderwidth => '0',
                        )->pack(-side => "right", -anchor => "e", -pad
+x => 3);

It may be a silly question, but I really haven't found a way to use .ico files instead of png. Any idea where I can find something? Thank you
