Facebook saw 750 million photo uploads from its users over New Year’s Eve, tweeted Randi Zuckerberg, Facebook’s marketing director and (sister of Mark Zuckerberg).
“People celebrated New Year’s on Facebook by uploading a record number of photos — 750 million over NYE weekend alone!”
To give some context to that number, in July Facebook said that more than 100 million photos get uploaded every day (that average is higher now, obviously). Here’s another stat: Flickr had its 5 billionth photo uploaded in September 2010 — Facebook would get that in a week or two if photos were uploaded at the rate they were last weekend. That’s a little apples-to-oranges (though Facebook does now offer support for high quality image uploads), but it gives a sense of the scale of Facebook Photos.
