Picassa albums and Google+ albums are now integrated, as far as I can tell. Just upload your pictures to Google+. They will show up in Picassa. Permissions are transferred, too.
I use the Instant Upload feature in Google+. Works great.
So I should be forced to be a Google+ user just so I can upload my photos to Picasa? I'm boggling right now... ...
Google+ resizes photos, anyways, and they must be on Google+ if you want to avoid running into storage limitations at which point they'll be resized into something fiercely small. I was going to pay for PWA storage but not if it's broken on my device. My Vibrant from mid-2010 didn't have such a significant bug...
I've since moved everything to SkyDrive. It's superior to Google+/PWA and Drive all folled into one service. Plus I have 25GB there and it's more cross platform. There's an Android app now.
All I use Google+ for is as a Feed Agregator. It has basically replaced Google Reader and allowed me to Unlike sites like Engadget, Gizmodo, and TechCrunch on Facebook (so I see more actual Social Updates and less redundant "News" stuff on there).
This service is virtually useless compared to Facebook, anyways. There's nothing here that Facebook doesn't do with 50x the audience potential.
