It seems like Google is very much inspired with Bing’s new look and feature of custom backgrounds. Today on Google home page you can browse a gallery consisting of stunning background images. These images are collections from great artists and photographers. There are many incredible images from National Geographic also. Google is offering this to spread more awareness among the people about its recently introduced custom-background feature.
Since, all this effort of Google is to offer you personalization of your home page. So, you can still choose an image or photo from your computer or your Picasa photo album.
So what have you been waiting for? Google is offering this Gallery only for next 24 hours.
