Yes indeed! Since a single forward-char moves over the image when used
interactively, I got the impression that the image is only a single
character. From your code example, I see that this is not the case!

I think a very good solution would be to document the return value of
insert-image-file, i.e., to add to its description a statement such as:

    Returns list of absolute file name and number of characters
    inserted.

What do you think? Thank you very much for looking into this!

All the best,
Markus
