Google Images now recognizes Creative Commons and let’s you filter your searches based on the suite of licenses as well as other licenses.
Let’s say you’re a blogger. You’ve just returned from a trip to New York City, and you’re writing a post on New York landmarks. You want to illustrate your travel guide with an image — as the saying goes, a picture is worth a thousand words. It’s easy to find images of New York online. But you want to make sure that you don’t use images without the permission of their owners, and you can’t afford licensing fees for professional photographers.
Today, we’re launching a feature on Image Search to help you find images that you can use for free, while respecting the wishes of artists and creators. This feature allows you to restrict your Image Search results to images that have been tagged with licenses like Creative Commons, making it easier to discover images from across the web that you can share, use and even modify. Your search will also include works that have been tagged with other licenses, like GNU Free Documentation license, or are in the public domain.
A little late. I was expecting this about a year ago.

I find this feature pretty useful, though the no of clicks is too much, they should have added some direct option from Google image search page instead of advanced search.

It would have been nice to see the license in question in the search results along with the domain name and thumbnail, instead of having to hunt through the page itself to find it.
