Well, I can't see that a lack of volunteers to provide photos means no-one wants to see the tutorial. I can imagine a lot of people read the original post, and thought, "That sounds cool - but there's no point in me sending MY crappy photos - someone elese will send something better". And of course, if everyone thinks that, you get the observed result. Actually, it might be quite difficult to find really good photos that would be useful for this purpose. The average person standing around looking goofy is not necessarily a good model. One can do a lot without such reference models, using imagination instead.
