Flickr has enabled a new way to share Flickr photos with your friends on Facebook: you can now connect your Flickr and Facebook accounts, and every time you upload a public photo or video, your Facebook account will be automatically updated as well. To enable this feature, go to www.flickr.com/account?tab=extend and click “Connect”.
