Agkistrodon contortrix contortrix
Quelle: http://commons.wikimedia.org/wiki/File:Agkistrodon_contortrix_contortrix_CDC.png Autor: This image is taken from the Public Health Image Library (PHIL), a division of the CDC. The description of the image specifically states that it is in the public domain: "This image is in the public domain and thus free of any copyright restrictions. As a matter of courtesy we request that the content provider be credited and notified in any public or private usage of this image." It is credited to Edward J. Wozniak D.V.M., Ph.D. I downloaded the high-resolution TIFF from the website and re-saved it in the PNG format (compression level 9) using GIMP. This reduced the file size by about half while resulting in no loss of visual information. Original URL: [1]. Due to the extensive use of server-side scripting on the PHIL website, it is impossible to link directly to the image description page, but it can easily be located by going to this search page and entering the image ID (8130) in the search box. This work is in the public domain in the United States because it is a work of the United States Federal Government under the terms of Title 17, Chapter 1, Section 105 of the US Code. See Copyright. Note: This only applies to works of the Federal Government and not to the work of any individual U.S. state, territory, commonwealth, county, municipality, or any other subdivision. This template also does not apply to postage stamp designs published by the United States Postal Service since 1978. (See 206.02(b) of Compendium II: Copyright Office Practices). |
