Yes Joce, it was working for me too, until it wasn't. I do know what to do and was doing it with some success and then suddenly it stopped working! I think I am phrasing my question badly, I don't need to know how to post images, I want to know why it isn't working for me. Perhaps there is a box which need ticking/unticking.
I am on Windows 8.1 using Internet Explorer. If anyone has any ideas, I would be most grateful.
In the meantime, please imagine the funny dog I am trying to post.
