A few nice image library images I found:

To animate view the image at original resolution (click all sizes) or simply scroll down.
The purpose here is not to duplicate the original image, from the Library of Congress website, but to generate a downloadable animated gif to assist viewing and presentation.
The library of congress offers a multitude of historical images online, many needing no license to redistribute. The original image is titled Washington, District of Columbia. Tent life of the 31st Penn. Inf. (later, 82d Penn. Inf.) at Queen's farm, vicinity of Fort Slocum. It has no known restrictions on publication. There are several copies of the left image on flickr, but I could not locate an extant gif. Library of Congress call number: LC-B811- 2406[P&P]
Image rotations, resizing, alignment, and animated gif generation done with StereoPhotoMaker, a freeware program by Masuji Suto & David Sykes.
