Why? Photo backup with Dropbox is better.
When google+ first offer photo backup, I could direct link it and post on the forum. Now I can't do it any more. Dropbox is better. At least I have them on my laptop.
i dont want 20 different things to worry about. If i want to share albums or photos its much easier through Google... and there isn't a cell phone that has a sensor yet that deserves to be higher then 2048px. That being said, I hope you'll be able to adjust it (and lose your free space) in the future. I pay for space on Google, i dont care about it being free
