Another change is that Google Profiles include a new tab for Picasa Web Albums, but it's not enabled by default and it's not available if you don't link your Google Profile with Picasa Web. "Your profile and scrapbook photos already make it easier for people to get to know you, but we want to do more to help you showcase your favorite pics. By choosing to show the PicasaWeb tab, you will enable visitors to see your public albums. Private albums will remain visible to only the people you've shared them with directly."
