If you need to find photos or graphics that have less restrictions than a fully copyrighted image, Yahoo! is making that easier with a new Creative Commons filter on its image search. Creative Commons does not mean the creator signs away all rights on their content, but they do open it up to greater use.
For example, bloggers flock to Flickr for Creative Commons images that they can use freely on their blogs to complement their writing. Usually all that's needed is a simple attribution to the user who uploaded the image to Flickr.
Of course, Flickr, which Yahoo! acquired in 2005, isn't the only place Creative Commons images can be found. That's why it's nice to have a filter on a broader image search.
