General Support: How to install/word with plogger?

Hi! I'm new in this website building thing haha..

Everything from the plogger map, i did put that on my ftp.
And when i'm going to the _install.php file:
www.aravath.nl/bonaire/foto/_install.php

I see this:
<?php require("gallery.php"); ?>
<?php the_gallery_head(); ?>
<?php the_gallery(); ?> Plogger has already been installed!

But how do I have now further so that I can upload photo's?


Thanks for your help!
