I have some of your same concerns. I can't even figure out how to get a blingee to post in private or visitor messages and have probably tried for hours and gotten help from patient YT friends. Still...nothin.
I have a camera, but I really think my new iPhone takes better pics. And the smile box...well, I'll just have to hope miracles will occur.
I console myself that it will be fun to see things no matter how people post pics.
