GNOME Photos in version 3.9.4 added support for sync photos (and albums?) from Flickr and Facebook. Photos already had support for OwnCloud, but Flickr is a more wide used solution to store your images. Version 3.9.4 is the first release of Photos for 3.9.x unstable series.
Pickup Flickr accounts from GNOME Online Accounts and let the user access photos from Flickr. This should use Grilo’s Flickr plugin for the protocol / API implementation.
How it works?
You just need to add your Flickr and Facebook accounts in GOA, and GNOME Photos will do all the rest for you.
