LAST YEAR Flickr, a photo-sharing site, announced it would cut its free storage from 1 terabyte (more than 200,000 images) to just to 1,000 items. Starting this month, many users may find that their content is in danger of being deleted.

Flickr Commons photos will not be deleted. Anything uploaded with a CC license before November 1, 2018, won’t be deleted, but users will need to upgrade to Pro to upload more than 1,000 photos or videos.
