def render(context)
  # Jekyll passes in a mostly undocumented context object, which appears to
  # hold the entire site, including configuration and the _data dir.
  PictureTag.context = context

  # The instruction set depends on both the context and the tag parameters:
  PictureTag.instructions = Instructions::Set.new(@raw_params)

  # We need to explicitly prevent jekyll from overwriting our generated
  # files:
  Utils.keep_files

  # Return a string:
  PictureTag.output_class.new.to_s
