Facebook is trying to bring the world's poor online (and onto its platform) with Internet.org, but as a report on the foundation's progress confirms, it's already a staggeringly large presence for the rest of us. In a white paper about making pages and apps more efficient, Facebook used its photo volume as a case study, revealing some big numbers. Every day, Facebook's 1.15 billion user base uploads an average of 350 million photos, adding up to a total of 250 billion photos uploaded since the site's launch.

Photos themselves are a relatively small part of the picture. Facebook says that 4.75 billion total pieces of content — a category encompassing photos, comments, and status updates — are posted every day; 4.5 billion "Likes" and 10 billion messages are sent over the same period. Even so, the numbers dwarf other sites. Facebook subsidiary Instagram says it averages 55 million photo uploads a day, with a total of 16 billion photos. And Flickr sees only 3.5 million photos added daily with 8 billion added in total, though it's geared towards a somewhat different crowd than Facebook or Instagram lifeloggers.

Facebook has previously cited the 350 million daily number, but its photo library has grown slightly from February, when it reported a total of 240 billion images. And all those uploads come at a major data cost: its total infrastructure contains 250 petabytes of data.
