It's easy to add Photobucket to your Newsfeed on Facebook. Click the "settings" button beneath the "What's on your mind?" text field. Choose Photobucket, and enter your Photobucket account name. Your account has to be public for this to work.
Now, whenever you upload to your Photobucket account, an alert appears in your Newsfeed. A great way to get people to stay up to date with all your photos and videos!
