Dude you are the freaking best!

It seems to have stopped working

Ah, I have discovered the problem: When I select one of the related images and click on "view image" it only shows me the main image, not the related image that I've selected

Dude thank you so much you freaking rule

It works in Chrome but it does not work in Firefox.The "View Image" button does not appear.

Stopped working for me recently as well. This userscript make-gis-great-again works though.

I should have fixed the current problem. Don't know about Firefox, though.

make-gis-great-again doesn't include the image search feature, but maybe I can modify it. This script seems to break more often than that one.

Google changed things and it no longer works. Any plans to fix?

@gitguys

... Pending an update, I've switched myself to

https://greasyfork.org/el/scripts/38953-google-image-view-image-button

It works (at least for now; no doubt evil Google will break things again at first chance...) !
