Why we're changing Flickr free accounts
Just got around to upgrading my Flickr account to avoid having all my photos deleted next year:
Free members with more than 1,000 photos or videos uploaded to Flickr will no longer be able to upload new content after Tuesday, January 8, 2019 unless they upgrade to Pro. After February 5, 2019, free accounts that contain over 1,000 photos or videos will have content deleted – starting from oldest to newest date uploaded – to meet the new limit.
