Studies by OKCupid have analyzed thousands of profile pictures to find out what photos are the most attractive.
One striking conclusion: The way you smile matters.
For women, it is better to smile, but women who smile in a flirty way toward the camera get more messages. The worst thing women can do is flirt away from the camera.
For men, the most effective photos have them looking away from the camera and not smiling. Men should also never flirt away from the camera.
