It’s been just four years since Photobucket launched, and they’re already celebrating 50 MILLION users! That’s quite the accomplishment, and to help celebrate, they’re offering their users a free gift: 10 free 4×6 prints. That means that if every one of the 50 million members takes advantage of the free photos, Photobucket will have given away over five hundred million photos!

Photobucket has had an interesting year with both ups and downs. You may recall back in April when they found themselves feuding again with MySpace. Shortly after their little fight, they were friends again, and shortly after that, Fox Interactive Media acquired them. As you know, Fox is a subsidiary of News Corp. who also owns MySpace. They ended up getting acquired for $250 million, and they’re valued between $300–$400+ million.

So besides the fact that they just broke 50 million users, they also have an impressive amount of photos uploaded to their site. Right now the number is sitting at over 3.4 billion and just continues to grow! As of June, they ranked #47 in the Top 100 Global Sites per comScore’s Media Metrix.

To take advantage of your 10 free prints, you’ll need to visit their online store. All it takes is selecting your prints and then entering in a coupon code to get the credit. You will be responsible for paying the shipping charges, but they say it should only cost you a couple of bucks to mail.

Congrats Photobucket, and here’s to 50 Million more users!
