Accessibility: confusion between caption and alternative text leads to badly accessible images about zmarkdown HOT 1 OPEN

I think we already mentioned this subject somewhere; anyway, I agree on the problem: the way we currently handle alternative texts and captions is misleading.
However, before changing this behavior, we need to think about what to do with the LaTeX, because we currently do not render the alternative text in LaTeX anywhere else than in the image caption, as far as I know (when no caption is given, otherwise it is not displayed at all).

Do you have an idea of what would be a good way to integrate this alternative text in LaTeX?
Depending on what is chosen, implementation of ZMarkdown side could be more or less complicated, and we might also decide to update the template.

As a final thought, I shall note that this is a non-backward-compatible change, so might wait a bit before being released, even if changes are ready soon.
