can anybody recommend a good image search for firefox or app, it needs to be search from an image on your hard drive and be easy to use
I've been using Tineye: https://www.tineye.com/ I don't know if it will suit your needs but it's better than nothing. There are also plugins for Chrome and Firefox.
I've used Google's image search in past to upload and search for specific image. I usually got good results.
