The latest Clues for the IE8 point over to twitter and Flickr, saying that there was news that Bing is the first search engine to integrate results from Flickr and Twitter.
Flickr has launched Twitter integration. The Flickr Blog reports that Twitter functionality has been added to the photo management tool.
You can upload photos to both Flickr and Twitter, or use the functionality to tweet about an already existing photograph. The system will automatically shorten the url using a “flic.kr” URL.
Getting started is simple enough and instructions can be found here.
