As a recruiter I spend quite a bit of time looking at people's profiles on LinkedIn. Of course I want to see what the potential candidates look like as well as what their experience is. 

It's been proven over and over again that it only takes a fraction of a second to form an opinion of someone by just looking at a person's face.

There are so many ideas on how to chose a profile photo for your professional networking/social profile (personally, for my own profile picture I cropped a photo  from a photo-shoot I did with my one-week-old baby because at that stage it was the most recent semi-professional photo I had of myself that looked like me) but what does the research say, what are the secrets behind choosing a great profile picture of yourself? 

There are some good tips in the article below. Most of these ideas are common sense, but it is still worth a read (from my experience, whoever came up with a "common sense" phrase was a comedian, because common sense is not actually that common).
