Great - although could use more 'find' results Rated 4 out of 5 stars
Technically, works like a charm. Functionally seems like it hasn't crawled the biggest portion of pic on the net.This review is for a previous version of the add-on (1.1.1-signed).
TinEye keeps crawling
TinEye indexes images on the web and if it has not found some images that's because we haven't indexed them yet. Facebook and most other social networking sites don't allow indexing of their images, so we can't find images on a social networking site.
We are constantly crawling the web and expanding TinEye's index. You can see updates on our index size at http://tineye.com/updates
