Google has introduced a background image on the search engine’s homepage to enable users to customise Google.com with their own image, but many users have been frustrated and likes to remove it.
To remove the background image, registered Google users are able to sign in to their Google account and then click the ‘remove background image’ link in the bottom-left hand corner of the screen. Update: This solution appears to be data-centre dependent.
Alternatively, you may use Google’s SSL-encrypted site, which is currently in beta at https://www.google.com/.
If you are not a registered Google user, you may either sign up to Google and follow the above instructions, or wait 24 hours for the images to disappear.
