Of course some strange messages like “Notice: Undefined index: level in /serv/host/siko/gallery/gallery.php on line 37” [ i dont know what the hack is that ] but it works ….
The readme is :
To integrate Plogger into your website, place the following PHP statements in the HTML document you wish display the gallery:

First line of HTML file -><?php require(“gallery.php”); ?>
In HEAD section of HTML -> <?php the_gallery_head(); ?>
Somewhere in BODY section -> <?php the_gallery(); ?>
