Installation: Problem integrating Gallery into my web site. Please help me!

Please help. Unable to integrate the gallery to the page. I tried different ways - get a blank page.
Do I understand correctly that in the html code of the page you want to insert the following:

First line of the .php file -> <?php require("path/to/plogger.php"); ?>
In the HEAD section -><?php the_plogger_head(); ?>
In the BODY section where you want the gallery - <?php the_plogger_gallery(); ?>

By doing this, I get a blank page (((
