As you may know, Google has removed the View Image button from the Image Search, but the users can still view photos by right-clicking them and choosing the open image in new tab option.
I have noticed this change a few days ago, but I have initially thought that my browser behaves that way on Ubuntu.
Despite this, the community has found a quick fix for restoring the button back.
Use Startpage (Google-based search engine) to search images:
The easiest way to view images just like before is to use Startpage as your default search page.
Install the View Image extensions for Chrome and Firefox:
If you are using Chrome or Firefox, you can restore the View Image button by installing a browser extension, for free.
I have decided to use Startpage for photo viewing and downloading, due to the fact that my Palemoon does not support the extension.
