LONDON (Reuters) - Google Inc received the royal seal of approval on Thursday when it added a picture of the Queen to the logo on its British homepage to mark her visit to its London offices on Thursday.

The image, known as a Google Doodle, shows the Queen in profile and a golden crown above the letter E of Google.

The Queen and the Duke of Edinburgh will tour the Internet search giant’s British headquarters, a short walk from Buckingham Palace in central London.

The royal party will meet Google executives and hear about the company’s search engine, advertising and mobile phone technology. They will also learn how Google Earth, an online map, is being used to help save the Amazon rainforest.

The Queen will then be invited to upload a video to the royal family’s official channel on YouTube, the video-sharing site owned by Google. The address is www.youtube.com/theroyalchannel.
