Rated 4 out of 5 stars

The only thing that's missing in my opinion is the option to easily save the photo and/or open it in a new window with the push of a button. Otherwise, it's a great add-on!

This review is for a previous version of the add-on (2.4.3.1-signed). 

Press 's' to save the popped-up image. Press 'n' to open it in a new window or 't' to open it in a new tab.
