How to blind reverse image search engines
First thing's first, get a selection of images you want to use.
Visit
https://images.google.com/ to reverse image search that image so you can see what happens. Scroll down and chances are your image is there.
How do you get around that?
Go to
https://crop.imageonline.co/ and click on flip image. Flip your image horizontally.
Next, crop your image just enough to make the image a bit different.
Now go to
https://images.google.com/ and try again.
If it's still showing and you need a last resort, go back to
https://crop.imageonline.co/ and select "Color photo to B&W image".
Chances are google reverse image search won't pick up on this image anymore due to the change in color.
HOWEVER, THIS IS LAST RESORT!!! It's suspicious to have all your photos with black and white, so one or two photos is fine if needed.
Any questions, ask in the comments. Otherwise, enjoy!
