Better chance of getting job if you put your picture on your C.V?

Is it better to also include a picture, like a headshot, with your C.V and can you do that? Or do they prefer not to include your picture on the C.V?? I really want to increase my chances of getting a job! But are there some special rules that says you shouldn't? Thanks.

It never made a difference to me. I focus on the skills and experience of the candidates and on their ability to interview. I don't think including or not including a picture on your CV would make any difference.
