Prove it.
IIRC, there are two in this picture book, one of me covered in charcoal dust and the other showing how thigh packs work together with a chest holster and camelback waterbag.
The photo on the site for my first book was shot by my daughter, but it's typical of author-on-the-flyleaf photos. I did a Google search that apparently eludes your capabilities and found three images, and two were the same. So you won't find much there to throw mud at.
On my FR page you can get my name and search the web yourself but I'd suspect you'll find the same.
I can't think of any others. Any further stupid questions?
