Check out the LiveUpload to Facebook plug-in for publishing from Windows Live Photo Gallery. It allows you to upload photos directly from Windows Live Photo Gallery to Facebook. It even preserves the people tags you added in Photo Gallery and matches them up with your Facebook friends.
This is wonderful news! But, it came too late for me! I loaded up pictures onto my Facebook page yesterday! Anyway, it is very nice that Windows Live is continuously making things easier for us to interact with the rest of the internet.
Hopefully, I can save you the effort that I did. Find out more about the plug-in here: A Photo Gallery plug-in for Facebook.
Happy photo uploading!
