Reverse image searches

recently I have been experimenting with reverse image searches, these are search engines that look for image matches rather than word matches but also you can add words to the search so I could upload a pic of Poole pottery for example and add the words "Poole Pottery" the search engine then attempts to find matches that were posted online.
I have tried a few distinctive pots that I posted on the forum and to my delight I was shown exactly where to find my post.
I had the most success with Google but there are several engines out there

I've tried it a couple of times when searching for similar items but not had much success with it, other than for it to show me my own picture if I've uploaded it elsewhere.
I have found, though, that Google now sometimes throws up search items off Facebook, which it never did before.

I would love Kirk to come up if I did the search

seems I look more like Jagger and Jacko

If I were you I would be more worried about looking like blossom petal

It can be useful and have had success, but tried it once with a pottery mark and got pies!

YUM!
