Google's image search is one of the fastest ways to find a picture of just about anything, but that doesn't mean you can use all of the images you find on your website or blog. Google just made it a lot easier, though, by adding the option to search for Creative Commons-licensed images.Read the entire article here.
The terms of Creative Common licenses vary, but if you go to "advanced image search," you can choose to filter images by the reuse and modification privileges their licenses allow. If you search for Creative Commons images, Google will also throw in other images that are licensed under the GNU Free Documentation license or in the public domain. Google says it's still a user's responsibility to click through and verify that the licensing information is actually correct, but that's still a lot easier than sifting through thousands of image results yourself, looking for one you can use.
