Google Image Search is getting a facelift. Changes include inline panel of results and more transparent display of metadata relating to the image, as well as no longer loading the background page for each selected image.
Google's Webmaster Central Blog outlines the changes, which Google says will roll out "in the next few days". The interface changes to display images more prominently, but the site that it's displayed upon is no longer loaded in the background. Google states that it has made this change to both speed up image searches and reduce server load on originating pages, with the idea being that you'll spot the original page from the links on the side. It does a good job of making the origin of images clearer; whether users will pay any more attention is another matter.
