If you use Chrome, right click on the image and select "Search Image with Google". In the right hand panel, you can normally use the button "Find image source" to see where it's been posted, but in this instance, you can look just below the image in the right panel, and see the "ThisVid" link.
If you're on another browser (might not work on a mobile phone, though probably works with Android), copy the image (right click on the image >> copy image [not image address]). Go to
www.Google.com on the right of the search bar, click the camera picture. When the page loads, click on the word "Drag" (just to make sure the focus is set). Press Paste (Ctrl+V on Windows computers), then click "Find Image Source" above the image.
For the pic you're looking for, it comes up to:
