Who owns your pictures?
Virgin Mobile in Australia is causing a stir with their ad campaign that reuses photos from Flickr. CNN reports of a person who is going to sue Virgin Mobile for using her picture in the ad campaign. It would be a good time for the Flickr users to pay attention to a feature that lets them select how they are publishing their photos. Technically the photos Virgin Mobile is using are all in the public domain as the users have opted not to apply a Creative Commons license that denies commercial use of their photos.
Don’t forget, things you publish become public. If you want some control over how your content may be reused take a moment to figure out what Creative Commons license is best for you.
