Google Images Has Hidden Features

window.document.getElementById(‘post-3845’).parentNode.className += ‘ adhesive_post’;Philipp reported last week that Google is working on image recognition features for Google Images, so that Images will be able to finally recongize what is in photos, not just the names and associated text/metadata, and that two of those features may already be live. You won’t find them anywhere in the Google Images interface, but simply adding a string to the URL will get you access.
If you want to see only images containing the faces of people, add &imgtype=face to the end of the URL.
If you want to see only images from news articles, add &imgtype=news to the end of the URL.
To try it out, Philipp coded a search box that lets you choose from the new parameters. Try it out at the end of his post.
There’s also a Greasemonkey script to add it permanently to your Google Images page.
