Microsoft this week is introducing a new Windows Live plug-ins website, which allows users to download and submit plug-ins for Windows Live Photo Gallery, Movie Maker, and Writer.

From the new plug-ins site, users can download and add the Inkubook Photo Book Uploader to Windows Live Photo Gallery to create high quality photo books, or get the Insert Video plug-in for Windows Live Writer, which allows users to insert videos into their blog posts from places like YouTube and MySpace. Microsoft has also made it easier for developers to contribute new plug-ins to the community, and encourages them to create and upload their own plug-ins.

The plug-ins help Windows Live users to connect their Windows Live experiences to the other services they use. Users can connect Messenger to Facebook, MySpace and LinkedIn, Hotmail lets users bring in their email from Gmail and Yahoo! Plus, and WordPress.com powers a blogging for Windows Live users.
