On Tuesday night, engineer Doug Beaver wrote a blog post announcing that the total count of photos on the site now stands at about 10 billion. The social network announced informally in August that it has hit 100 million active users worldwide.
To compare, the News Corp.-owned Photobucket, which has a real-time ticker of photos uploaded, stood at slightly less than 6.2 billion photos on Wednesday morning. Flickr, which is owned by Yahoo, hit 2 billion photos just less than a year ago.
"To celebrate (the photo-hosting milestone), we got a bunch of cupcakes and handed them out to our engineering and operations groups," the post read. "One of our engineers calculated that if we had gotten one cupcake for each of our photos, and lined them up side by side, the line could reach halfway to the moon."
