Having created PNG images of playing cards and used GIMP to 'transparent' curved corners, I having problems with Perl/Tk failing to allow the background to be shown in these 'transparent' areas, instead I am seeing four white areas. There is now problem is displayed in HTML: (my HTML code is not showing correctly so for imgage please read img.) 

<html>
</p>
<p>
<body bgcolor="#E6E6FA">
</p>
<p>
<img src="Cards/00.png">
</p>
<p>
<img src="Cards/20.png">
</p>
<p>
<img src="Cards/50.png">
</p>

...... etc (see:- http://i.imgur.com/wlnHn6h.png) but the 'failing' code, of the form: 
    $Card_Back = $main->Photo( '-format' => 'png',
                         -file    => $dir . "Cards/00.png");

[download]
produces this type of display: http://i.imgur.com/6N13iKX.png Thanks for any help, Bill
