Google has introduced a new feature for its mobile Image Search offering. The feature is “Popular Images,” and lets Android and iPhone users browse popular images (go figure). The Popular Images feature comes in the form of a link just under the search box on the Google Image Search page. When clicked, it brings up a categorized list of image searches and corresponding images. The queries are categorized automatically with an algorithm, which Google says will continue to improve over time.
