Thanks again! I just want to point out for anyone referencing this later on
that, in #1 of the captions examples, the template should include <img
src={{$:/*lightBox*/currentImage##img}} /> and
{{$:/*lightBox*/currentImage##caption}}
instead of "{{$:/state..." but of course you can name it according to your
own organizational preferences.
Thanks again,
Michael
