Disable Jekyll Picture Tag
disabled: (true|false|environment|array of environments)
disabled: [development, staging]
Disable image and markup generation entirely. Useful for debugging, or to speed up site builds when you're working on something else.
Hint: If you're going to toggle this frequently, you might use a Jekyll Environment. Set this to something like
nopics, and then start Jekyll with
JEKYLL_ENV=nopics bundle exec jekyll serve.
