Share Picasa web album with friends who are not in Google+

Since Google+ came into the picture, I found it slightly difficult to share Picasa web albums with friends who don't have a Google+ account. However, when I clicked on the 'Share' button, a popup window appeared with an option to share my album with G+ friends. There was also a link 'Share via email only' in the bottom of the window. I clicked on that link and .. voila ! I can now share Picasa web albums with anyone.
