Ubuntu 12.10 scheduled to be released this October will include Gwibber and Photos lens by default. These lenses add up to the existing collection of lenses namely applications, files, music and videos.
These lenses were not included in previous releases due to bugs and other stability issues. While Gwibber lens can be readily installed from Ubuntu Software Center, it remains a secret of how the Photos lens will look like.
