I use Picasa Web Albums for my family photos and Flickr for my "artisitic" photos. Now when I go to picasaweb.google.com I find that I am actually taken to Google+. There is a small message at the top highlighted in yellow saying click to go to Picasa Web Albums. It is just a URL with an option.
I have saved that as a boomark so I can go directly to Picasa Web Albums.
