Yahoo said today it has launched a royal wedding website for the marriage of Prince William and Kate Middleton.

The royal wedding website features articles, photo galleries, and videos. A digital guestbook has been created in Prince William and Kate’s honor so people can offer their advice to the couple. A number of celebrities have already added their advice and wishes to the Royal Wedding Yahoo Guestbook, and more will contribute in the future.

Yahoo says its royal wedding website is an extension of Shine From Yahoo, a website for women’s lifestyle content.

Features of the Royal Wedding website include:

*Photo galleries: View photos of the couple’s courtship, Kate Middleton as a child.

*Wedding live stream.

*Video: Yahoo will feature video from Associated Press, Reuters, and ABC News, along with original video content including a joint ABC News/Yahoo News Web show called “Wedding Royale.”

*A mobile site.

*A chance to enter the “Live It Up Like Royalty” sweepstakes: By signing the Royal Wedding Yahoo! Guestbook or by “liking” Shine from Yahoo on Facebook, users will automatically be entered to win a trip to Las Vegas.

Additionally, Flickr features The Official British Monarchy Flickr stream.
