Take a look at Tk::Thumbnail, which can easily be used to render your list of pictures.
The thumbnails are by default clickable.
use Tk;
use Tk::Thumbnail;
use strict;
my @thumbnails = ("ant_logo_small.gif", "current.gif", "group-logo.gif
+");
my $mw = MainWindow->new;
$mw->geometry("600x400");
my $thumb = $mw->Thumbnail(-images => \@thumbnails, -labels =>0, -widt
+h => '50', -height => '50', -command =>\&openwin)->pack;
MainLoop;
sub openwin {
my $tw = MainWindow->new;
my $pic = $tw->Photo(-file=>$_[1]);
$tw->Label(-image => $pic)->pack;
};
