How To Change Google Background With Your Own Photos

I've been using Google search engine a lot but I am not paying attention of the features on the front page every time I am doing my search. Then one night when I opened up the browser, I noticed the feature on the bottom left corner that read " Change Background Image". So I pointed my mouse and clicked the link and suddenly a small window pop-up with so many options to choose from (by the way, you should need a Google account). You will see four selections on this window like; "From My Computer", "My Picasa Web Photos", "Public Gallery", and "Editors Picks". 

                         



   Here is the typical Google's web browser 























Here is the type of window you will see once you clicked the "Change Background Image" 
Okey! I will use the face of the woman and the puppy as my new background. As shown here on the next photos.
