Did you use photobucket? They changed some policy that affects pictures you try to share (sorry, I don't understand the problem very thoroughly). I had other problems with them for a while and finally changed to a blog which I like much better. If that's your problem, I'm not sure what you can do about it other than try to replace the pictures in a different format on your tutorial.
