In computer-related languages, the first thing is usually the "0" thing.
Javascript, for example, numbers the initial item in the images array (-and
all arrays) "0". It can be argued that a zero item should be an empty item
but the logical fact is that even an empty item is one part of the set of
"whatever" selected from all possible parts of the set of "whatever". An
empty list is conceptually still a list if originally defined so and not
nothing (-using the double negative in its correct form.)
