Flickr Groups

Flickr Groups are themed image collections created by members of the Flickr photograph-sharing community. There are thousands of Flickr Groups, and more are created daily. The size and quality of images within the groups varies, but overall I am impressed with the images I find there. Copyright protection varies by photographer. A very popular protection on the site is the Creative Commons license, which allows anyone to use, distribute, and change the photograph as long as attribution is given to the creator. To the right of each photograph the copyright information is displayed.
Selected groups:
- Art & Florence
- Renaissance

Wikimedia Commons

Wikimedia Commons is a huge media repository maintained by volunteers. The website has hundreds of thousands of files of images, sounds, and videos for many disciplines. The Category: Art section allows you to browse images from various access points, such as country, culture, genre, period, artist, collectors, etc. Navigation through the various links of the site can be time-consuming, so if you are searching for a specific artwork or artist it would be best to use the search feature (since images are hidden until you get to the most specific category). All of the media files on the site are supposed to be available for educational use-- the specific license conditions of each file can be found on their description pages.
