Now there’s a free download that comes with two ways for Mac users to upload photos to Picasa Web Albums — from directly within iPhoto or using drag-and-drop from a standalone application

For iPhoto™
The Picasa Web Albums Exporter is a plug-in that lives right inside iPhoto™. Select photos, choose Export in the File or Share menu, and upload them directly to your web album.

For a standalone application
The Picasa Web Albums Uploader is a small application just for uploading your photos to your web album  — simply drag photos from the Finder and click the Upload button. Use this method if you want to upload photos or folders of photos that aren’t in iPhoto™, add captions to your photos before you upload them, and search your Mac for recently added photos.
