This looks interesting! I'll dig a little deeper when I have time. http://googleblog.blogspot.co.uk/2015/05/picture-this-fresh-approach-to-photos.html
Interesting. I took a quick look and uploaded a few jpgs. Seems to work nice and easy and you can create albums and collections, though have only tried with an album so far. You can share photos but seems to be only the http line. Not sure if that works with the forum.
