Agreed.
Which is why it is od that no one has anaged to give a direct answer to my question about what information the picture adds to the article. --
I believe you got an answer from me. And David Gerard's was I think very direct: it demonstrates that it's possible. But illustrations aren't required to be absolutely necessary to appear in an article. I have blind friends who seem to manage very well without sight, so I'm confident that I don't need to use my eyes. But I'm glad I've got them and one of the reasons is that I can look at pictures.
