I really like your idea, and it's more consistent with the Org syntax, since (as you say) the images behave like images and it is not necessary to enter the options via marks within the link description, which is somewhat hacky. I think your idea could also be adapted to LaTeX (and HTML) backends... Best regards, Juan Manuel
