Unfortunately with Beta2, you can't just drop the "integration code" into one of your pages anywhere on the server. We've fixed this for the next version, but for now you will need to drop in your gallery within the Plogger directory itself.
Easy tip: Just modify /plogger/index.php so that it looks like one of your webpages. The three lines of code are already there, just build around it. This will ensure all your pathnames are resolving properly and should solve your problem.
