Back in 2017, I requested all photos of Microsoft founder Bill Gates from the George W. Bush Presidential Library and Museum. The Library sent a letter explaining that they’d found 36 photos and released all 36 photos in full.
From the National Archives description of FOIA number 2017-0200-F:
Photographs of a lunch and Oval Office photo opportunity with Bill Gates and President George W. Bush on March 15, 2006. This event also included Mrs. Laura Bush and Mike Gerson. In addition, there are photographs of President George W. Bush and Bill Gates at a reception with CEO sponsors of the 2008 United States Summer Olympic Team at the Ambassador's Residence in Beijing, China on August 9, 2008. Also pictured at this event is Ms. Barbara Bush. These materials are from the White House Photo System – Presidential Search and Access Set.
All images are low-resolution but high-resolution images can be ordered directly from the GW Bush Library for a fee. All photos are in the public domain and can be used without further permission. They should be credited to the George W. Bush Presidential Library and Museum.
