I store my photos physically on disk in folders organized by date. I recently returned from a trip spanning several days, so I also added all the pictures from the dated folders to a single album in Picasa and synced it as a web album.
It was my understanding that Albums in Picasa were more of a logical grouping, whereas Folders are obviously a physical grouping on disk. However, when I updated the captions on the photos in the Folders, the captions of the photos in the Album were not updated and neither were the captions on the web album.
Am I just mistaken about how this should work? Is there a way to sync up the captions between the same pictures in Folders, Albums, and Web Albums?
