Great way to search for images or to find out where a image came from. i bet you be surprised to find out that most images came from different sources. some was stolen.

Provides every engine imaginable.

A must have add-on if you use reverse image search even occasionally. Moved recently from "Image Search Options" by Xamayon

Nothing not to love - does exactly what it says it does. While the image search platforms themselves may not always yield the results you want, Search by Image is a handy shortcut to have, and much faster than going to those sites manually. For me, it was something I didn't think I'd need until I needed it.
