I have a problem with editing some photo's. The problem is that those pictures are indexed by google images and other image search engine. If I chose to search by image with one of the photo's google will display the website which contains those photos. I want to modify those photo's so they don't appear on google images when I search them. I have tried to change colors, resize, add some text, change the exif but google images still detect them. I think it's more like a fingerprint of the photo that it needs to be modified. Anyone ideas?
