The OP has made her decision, and I hope some of the advice given will help her. My comment is on whether the camera-phobic should cooperate with family photos (assuming you don't have to perform some really stupid pose, of course). Now, cameras hate me, and I'm much happier on the side of the camera without a lens. The number of photos of myself that I like, I could count on one hand, and that includes the photo of me at 3 or 4 with Mom's makeup on my face. I also have no patience with people who photograph every single thing that stands still long enough; digital cameras have a lot to answer for there.
And yet . . .
I'm scanning old family photos and posting them to a Photobucket account for the nieces and nephews. Many times I have run across a photo of family members at some holiday or another, and smiled to see how young Nephew was, or what color Sister dyed her hair or wondered which of Niece's boyfriends that is. Sometimes there is a sulky, stringy-haired teenaged me. And my nephews and nieces, maybe even their children, will be just as delighted to see photos of that much younger me, as I am to see them.
Quick Public Service Annoucement: Please, please write names and the date on the back of photos. If you are sending photocards for Christmas, please incorporate the year into the greeting or write it on the back. If the picture is a jpg file, rename it with some clue about when and where. The biggest folder is going to be "Unknown People," because most of the people who I could ask about these anonymous photos are gone.
