Say: "Please don't post that on facebook" and all of the sudden you are a snob. Is this endemic to notions of being "real," "down to earth," or "not taking yourself too seriously?" For me, it is none of these things (OK, so maybe a little bit of the third). It is just that my sensibilities of privacy resemble the more developed European model which values informational self-determination.
This is not so much a question of vanity as it is control. Is it unfair for one to seek to control how they are perceived? I think this question highlights the gap between U.S. and European notions of privacy. Americans see privacy as a matter of liberty. Europeans see privacy as a matter of dignity.
Images and video are visual information about you. You very well may not want to have that information scattered to the four winds. Even in benign situations, lighting, what you are wearing, and other factors may yield images you do not approve of.
If one is not a public figure, should she not be able to assert that the only images of her on the web be images that she approves of? Like it or not, visual information posted to the web can profoundly indignify you. (extreme e.g., see the classic YouTube video of the "Star Wars kid" with the golf ball retriever emulating Darth Maul). But voicing any concern with this makes one a snob?
