What website can get me the name of a person, by posting only a photo of them?

You could try Google, but the chances of getting a good match for a non-celebrity are virtually nil.

If they are in Ghana... its a stolen picture.

The person is a celebrity. How do I submit the image to Google®™, so it can be compared or searched?

Go to google image search and click the camera icon, this allows for uploading
