Flickr? Photobucket? Think again. It’s Facebook. And they’re making huge gains with more than 10 billion photos uploaded to the site so far.
Facebook photo traffic has really exploded since their redesign added a photo tab to the main page. Meanwhile, Flickr is about to pass Photobucket in monthly users. Funny, I don’t think know a single person that actually uses Photobucket.
