Google has made its photo service independent of Google+ (as it used to be) and I think its a good move. My phone has always been set to upload any photo I take as soon as possible, automatically when wifi is available. Google has expanded their quotas for this service. You now get unlimited storage of images up to 16MP (mega pixels) and videos up to 1080p.
It's too bad Google+ didn't gain more traction, it's a much better setup than Facebook in my opinion.
The new site will make it easier to share pictures hosted there on other social media platforms.
