I got a flickrmail asking if a photo I took of Lily Tomlin, http://www.flickr.com/photos/cirne/140992347
could be used in her Wikipedia article, http://en.wikipedia.org/wiki/Lily_Tomlin and if so, then to put a CC license of only Attribution on it. Now this seemed strange to me because that photo (and most of mine) are already licensed as CC Attribution+Share-Alike+Non-Commercial. Wikipedia is non-profit, so why would this license be a problem. But then when I checked the submission requirements, http://en.wikipedia.org/wiki/Image:Replace_this_image_female.svg it states: "If you hold the copyright to an image (e.g. you photographed or drew it yourself) and would like Wikipedia to be able to use it, you will need to release it under a free license, such as the GNU Free Documentation License or the Creative Commons Attribution or Attribution/Share-alike licenses (versions 2.5 and earlier), which allow everyone to use, alter, and redistribute your work for any purpose, including commercial use. Do not use this form for images found somewhere on the Internet or created by someone else." Why does Wikipedia require commercial use of someones contributed media work? -- Enric
