50 non- public photos..... so that means absolutely 0 public photos without a paid account. They can go suck an egg. I was kinda hoping to utilize it more in the future. Maybe if I start making some money from my photos again someday.
No, it means the same 1000 limit for public photos, but only 50 for non-public.
In other words you need to pay if you:
1) use flickr to share more than 50 photos privately;
2) use flickr to share NSFW photos; or
3) use flickr to share more than 1000 photos publicly.
This means that photographers who use flickr to privately share portrait or wedding proofs with their clients, or other businesses who use flickr to privately share work with clients, will have to pay up.
It also means that if you are in charge of privately sharing the more than 50 photos from your last several big family reunions, you will also have to pay.
