There are two pictures that were taken of me since I was seventeen years old (I'm 46 now). The only two I know of in existence. One was for an article about five years ago, and the other was because the Google Street View car caught me before I could duck. The fact that she only has one picture is the most relatable thing about her, in my opinion.
But you're not serving the public in a arena where your credibility (history) needs to be known. I'm assuming you are an artist. She, on the other hand, is trying to convince us of something (searching for the TRUTH as she says). That's why her history and a few artifacts of her work (ie, pictures, etc.) are important. It doesn't matter what she looks like, really, but for instance a photo of her working with Art in the studio would go miles to show her credibilty and history....hope this explains a point of view.
