Is anyone able to successfully see their Picassa Web Albums through the phones gallery?
Google annoyingly changed the way gallery worked when they merged with camera. For awhile there were a couple work arounds depending on the gapps you flashed, but I that was back on cm10.0 or maybe even 9.0
There's a very easy solution. Grab something like Justpictures from Google play store and try it out. I've been using it for a couple years now. It's free, the dev is responsive and it'll let you add in a number of different accounts like Facebook and picasa.
Or just open the google plus app..cause that's what Google wants you to use now, but the interface kind of sucks, imo.
