Google is making easier to upload photos to orkut directly from Picasa. To get started, just install an orkut button on your Picasa program by downloading the free 'Share photos on orkut' plugin, that makes sharing your photos with your friends as easy as clicking a button. If your Internet browser asks your permission to launch the Picasa software, say "yes." Once Picasa opens, simply add orkut button. Next, just select photos you want to upload to orkut and click orkut button you've added to Picasa. You can upload your photos to an an existing orkut album, or create a new one. The photo uploads will begin, and a slider bar will show progress of your upload. Once it's complete, you'll be redirected to your orkut album page where you can share your photos with your friends, or set privacy levels for your new album.
