Photos do not belong on your CV/resume unless you're applying for a job where looks matter more than intellectual competency. The average resume is scanned for 60 seconds to determine if the candidate meets qualifications.
You could your photo on your LinkedIn profile (which you should create as part of your job search process if you haven't already created one). That's where I look for pictures of candidates and new coworkers.
If you are considered a qualified candidate, your social media presence will be reviewed. Make sure all your social media is cleaned up. We had a lovely co-op student who lost her position before she started because of the types of pictures on her Facebook account. (Drunk pictures from parties in college, racist comments on her wall posted by friends, etc.) Make sure that if someone Googles your name, they won't find something that you would be embarrassed to explain.
