I installed your plugin today. It's very good.
I have a problem when activate "Use the Google+ phototile style for album layout and thumbnail size selection"
Once activated, the container page shows this error:
Warning: Wrong parameter count for round() in /home/corpnews/public_html/fullpayload/wp-content/plugins/picasa-express-x2/picasa-express-2.php on line 2060
Any help would be appreciated.
