Lastly, we looked at our members and found a clear line between Free and Pro accounts: the overwhelming majority of Pros have more than 1,000 photos on Flickr, and more than 97% of Free members have fewer than 1,000. We believe we’ve landed on a fair and generous place to draw the line.
I'm a long time flickr user who has had a pro account off and on over the years. When Yahoo set the upload limit to 1TB I took the bait. Over the last 14 years, I have uploaded over 10,683 photos to flickr. Many of these images are embedded or linked to from my this website. Many of those links will break once Flickr started culling my photos down to 1000. And if I want to continue to use Flick I will have to cull the remainder to make room for new images. I need to find a way to find and remove all these Flickr links so that I am never in this position again. And then ... perhaps delete my flickr account.
