Goddamn Pinterest. No I don't want to sign up for Pinterest just to look at this pic that Google Image Search thinks is available to the general internet!
I haven't needed that, it just works when I click on the picture then right click on the drill down.
If you right click on the larger image that appears in the dark sidebar popout in Chrome(ium), and select 'View image..' that also works (most of the time).
Problem with that is you'll be downloading the Google cached image, not the source imagine, so the quality is usually worse.
