Google Mac team released an update of “Picasa Web Albums Uploader” which now includes the ability to easily export movies from iPhoto '08. This update also preserves geotagging information in your photos, so if you're lucky enough to have a camera that adds G.P.S. data to your snapshots, you can see them automatically mapped inside Picasa Web Albums.
“For Mac users, the Picasa Web Albums Uploaders are the fastest, easiest way to share photos (and now movies!) on Picasa Web Albums. Like earlier versions, the download provides you with both an iPhoto plugin, as well as a standalone application.”
Visit the download page to get the latest version, and don't hesitate to give us feedback about the uploaders at the Picasa Help discussion group.
