I know some providers don't worry about people recognizing them, but others really don't want anyone who hasn't seen them in person knowing what they look like.
BUT when you publish your pictures with the face blurred out, make sure that tat of the USS Enterprise across your shoulders doesn't show. Seriously though, I had to PM someone last week after seeing her in "the mall" and recognizing that very distinctive tat (no, not The Big E).
I guess if you have something that looks like what other people have that won't be a problem, but think about what shows.
