Behold is a search engine that is designed to help you find the best Creative Commons licensed images for your blog, student projects, or presentations. Behold searches the catalog of more than one million Creative Commons licensed images on Flickr. What makes Behold different is that Behold searches not just by image tag but also by the quality of the content of the images. Behold uses both aesthetic and technical quality indicators to find some of the best images available online.
