Pretty good. It does what it needs to. Nothing more, nothing less. (Also I almost gave a 1 star review then I decided to use my brain and refresh the page I was on (I had been on it when I installed the extension) and sure enough it worked. So, my apologies for being stupid.)
It's very inconsistent. It shows overlays with the alt text of some images on a page, but not all of them. PS: I wish I could give it a zero star review instead of 1.
