OK on all that.
I have just downloaded the latest version of Firefox.
Height, width and border now works. At least I can now size images.
But "horizontal", "vertical" and "alt text" do not work.
This is for feedback to you, I am not complaing. I am sure that these will be fixed. The only thing I would suggest at this time is that if those last three dont work in any browser you might think about removing them as options for now, which I think I will have to do. I can tell people to use Firefox if they are using images but they will still get back to me if "alt text" does not work for example.
