Bill Patry calls attention to a dispute between photographer David Wise and MP Betty Hinton. Hinton used one of Wise's photographers in a campaign newsletter in February. The photograph was posted on Flickr and licensed using a Creative Commons license. Wise says he would not have allowed Hinton to use the photograph because he disagrees with "her campaign and political viewpoint." Moreover, the publication did not contain appropriate attribution. The case is reminiscent of a legal battle between Adam Curry and a Dutch magazine which ultimately led to a court upholding the validity of the Creative Commons license.
