Take your few seconds by checking out this trick:
Hold Down 'S' key in your keyboard and right click on any image of the page. So how it will work?
Have a look, how different browsers will react on this command.
Chrome: This immediately initiates a image search (i.e., searches Google for that image) in a new tab. It's a bit faster than right-clicking on an image and then selecting the search option.
Firefox: Opens the set image as desktop background window(as shown in the image below).
Internet Explorer: Opens the Save Image dialog to save the image to your Pictures folder.
Safari: Immediately highlights the "use image as desktop picture" option in the right-click menu.
