I’m pleased to see Flickr is going do away with their massive free storage:
Beginning January 8, 2019, Free accounts will be limited to 1,000 photos and videos. If you need unlimited storage, you’ll need to upgrade to Flickr Pro.
This is annoying for people who rely on it, but if a service is good then it’s worth paying for.
That said, and even though I do have a paid Flickr account, I think I’m going to stick to using my own Piwigo installation from now on.
