Might want to check yandex too. Lot of Russian and Ukrainian scammers steal from sites google doesn't index.
There is also a good plugin for finding stuff called tineye. Not only will it find the pics but may even find rotated and cropped ones.
I'm using Android smartphone. Not sure if I can install plugins there.
https://tineye.com/ is just a site too. You can use your browser to go to it then copy & paste an image URL into it.
