White House photostream on flickr

The White House photostream is on flickr. The White House started uploading official photos onto flickr in late April 2009.







This prompts the question: what are other executive departments and agencies posting in terms of images?

In addition to the White House, six Cabinet Departments have flickr photostreams.
State: http://www.flickr.com/photos/statephotos

Defense: http://www.flickr.com/photos/39955793@N07/

USDAgov: http://www.flickr.com/photos/usdagov

HUD Public Affairs: http://www.flickr.com/photos/opahud/

flickr labels the White House and Department of State photos as "US Government Work" while USDA says "Some rights reserved."

Below is the "US Government Work" disclaimer (reprinted from http://www.usa.gov/copyright.shtml):

Copyright Pertaining to US Government Work

A work that is a United States Government work, prepared by an officer or employee of the United States Government as part of that person's official duties, is not subject to copyright in the United States and there are no U.S. copyright restrictions on reproduction, derivative works, distribution, performance, or display of the work. Anyone may, without restriction under U.S. copyright laws,

reproduce the work in copies in print or in digital form;
prepare derivative works of the work;
perform the work publicly;
display the work;
distribute copies or digitally transfer the work to the public by sale or other transfer of ownership, or by rental, lease, or lending.

Caveats

Other persons may have rights either in the work itself or in how the work is used, such as publicity or privacy rights.
Not all work that appears on US Government Websites is considered to be a US Government work. Check with the content curator to see whether the work is a US Government Work. Works prepared for the United States Government by independent contractors may be protected by copyright, which may be owned by the independent contractor or by the United States Government. 
The United States Government Work designation is distinct from designations that apply to works of US state and local governments. Works of state and local governments may be protected by copyright. 
Copyright laws differ internationally. While a United States Government work is not protectable under United States copyright laws, the work may be protected under the copyright laws of other jurisdictions when used in other jurisdictions. Outside of the United States, the United States Government may assert copyright in United States Government works.
