Image search is an area of intense competition between Google, Yahoo, and now Bing. Today,Google Images
added some search options to make it easier to filter a search by color, type (face, photo, clip art, line drawing), and file size.
Most of these filters were available before in advanced search, but now they are available in the left-hand column. (A similar option column was introduced to the main search page in May, 2009). You can choose more than one option to automatically narrow down your search. Another option Google could add is sorting by images with a Creative Commons license. Italready does this in its advanced search options, but it is hidden there.
Yahoo and Bing have similar filtering options, Although Google’s color filter is the most advanced. It allows you to sort by 12 different colors, wheras Bing and Yahoo only let you sort by color or black-and-white images. Bing, however, does a better job with related searches, something Google is experimenting with in a slightly different way by actually trying to find And Yahoo has its own set of novel features in image search which Google doesn’t. You can compare the three with a search for “fruit” on Google Images, Yahoo Images, and Bing Images.
