Hi All,
I am creating a memory-game for my Kid. I would like to change the features of the button on Click. I am Not sure how to do it. My code is as follows.

use strict;
use Tk;
use Tk::Button;
require Tk::Photo;
my $top = new MainWindow;
my $myimage = $top->Photo(-format=>'bmp',-file=>"image/images2.bmp", -
+height=> 50, -width => 50);
for my $x (1..10)
{
    for my $y (1..10)
    {
    my $button = $top->Button();
    $button = $top->Button(-width => 5, -height=>2, -command => sub {c
+heck_status($x,$y)});
    $button->grid(-column=>$y,-row=>$x);
    }
}

sub check_status()
{
    my ($myx,$myy)=@_;
    ######### What to Write ??? ####

Can some guru, please tell me what command I can write between the commented lines so that I can assign '$myimage' to the same button.
Update:
Dear All,
Thanks to all of you, for your suggestions. I have almost completed my script. However I cannot understand, How to make Tk sleep?? Here when I click on 2nd button, I want image to appear atleast for 2 secs and then disappear. However the image is disappearing when you click 2nd button. Forgive me if my explaination is Not proper.

use strict;
use Tk;
use Tk::Button;
use Tk::Canvas;
use Tk::Photo;
use Tk::Splashscreen;
require Tk::Splash;
