I never understand why people include a photo of themselves on their CV.
For anyone applying to where I work please please please do not include a photo because I instantly know your age & ethnicity - things that I am not supposed to know about you.
Obviously I am going to see your face eventually (assuming you get to an on-site interview), but seeing it all before I get to talk to you in person can lead unconscious bias which is not good for anyone.
A bias has to be in favour of some people. Those people are usually the ones who include their photos.
Photos are also problematic, in so far as they allow the person screening the resumes to make hiring decisions -- even subconscious decisions -- on the basis of race, gender, ethnicity, apparent age, or even just physical appearance. I imagine that requiring photos of all candidates would be illegal, or at least highly actionable, in the US.
That being said, I don't think there are any rules against putting a photo in one's resume here. I'd just do it with extreme caution. I only see significant upside if you are a great looking person, or have a photo that just screams "Now THAT is a kick-ass professional!" Otherwise, there is just too much risk involved. Risk that you'll be weeded out for "fit" (read: "This person doesn't look like the kind of person who works here"), or for having a weird photo, or even for being the kind of person weird enough to include a photo (since again, photos are not the norm in the US).
I will say this much: as unorthodox as these visual resumes are, I kind of like them. They stand out, and they present the vital information in a much more digestible format than ye olde paper resume does. I just think the photo aspect is tricky. I'd also wonder whether real-life HR managers, recruiters, and hiring managers would grok this style, or whether they'd find it too eccentric. Recruiters are usually working within a mold, not trying to break one.
I know when I worked at big companies, by the time I saw a resume it had always been through at least one system, and often two or three; and any formatting that the applicant had done was long stripped out, leaving bizarre line breaks and other problems all over the place.
Same goes for age. In UK you don't need to put your age on the CV since law says you can't be discrimined by how old (or young) you are. But again, here in Italy is a very common practice.
However given this site is called "VisualCV" (emphasis on visual), I can see why people posting on there would want to include photos, in addition to the nice graphics and stuff.
