"The photo-sharing functionality in Hangouts is changing. Going forward, the ability to share photos and other multimedia in Hangouts Chat will be set by the Picasa Web Albums service rather than by the Google+ service. If Google+ is enabled in your domain, no further action is necessary. Google+ requires Picasa Web Albums so you can continue to share photos using Hangouts Chat just like you always have. If Google+ is not enabled for your domain and you want to use the photo-sharing functionality in Hangouts Chat, you must turn on the Picasa Web Albums service in your Admin console."
This change also affects regular Google users, since photos shared using Hangouts aren't added to Google Photos and you'll only find them in Picasa Web Albums when Google+ Photos will shut down. The same thing will happen with Blogger photos.
Picasa Web Albums and Google+ Photos served as a central hub for almost all the photos uploaded using Google services. This was great, since you could find all your photos in one place, but it also cluttered Picasa Web and Google+ Photos with albums automatically generated by Blogger, Google Hangouts and other services.
It looks like Picasa Web Albums is here to stay, at least for now.
