Well, Bernice, I am going to add my photo to my About page. It isn't professionally done, but it will suffice for now. I feel this "personalizes" a site, and potential clients get a visual of who they are committing their hard-earned cash to.
I don't plan on adding this to business cards, etc., just my website.
As far as security issues, I'm not real concerned. Wondering if I should be, though?
