Recognizing similar images

You guys have probably been wondering, why would I want to collect keywords for images?
As you may have noticed, you can search here if a photo that you have received has already been posted to this site. This photo search will work when you received exactly the same photo as someone else prior to you.
But the scammers are getting smarter. They take a photo of some model and slightly modify it. Each scammer may modify it in a different way. Usually they crop the image. Look at the two following ones:
Obviously the same image, but different size. The 'photo search' function will not recognize that these 2 photos are the same.
Now I added the ability to keep track of similar photos. The system will automatically recognize them based on the keywords. That is why it is not a good idea to add keywords like 'This is Natalia'. Instead the keywords should describe what you see on this picture- color of cloth, hair, etc.
I hope this will be helpful, in the long run. Only a small fraction of the images so far have received keywords. It's a lot of hard work.
Here are 2 other - 'similar' - pictures:
As you can see, they've been cropped to a different size and one has also been made 'brighter', for whatever reason. The keywords exposed them as being 'identical'.
