Hi !

On main page > Specials > Calendar > Select a month, I've this :

Notice: Undefined index: rotation in http://mygallery/piwigo24rc2/include/derivative.inc.php on line 63

This happens only for pictures without EXIF metadata (my pictures show only IPTC metadata) and on calendar month view.

I'm waiting for validation before I add it in bugtracker ;-)
