@arianna-merritt The new pattern is supposed to simplify the use of complex images. I was wondering if attribute like file, caption, summary and content are enough self-explanatory compare to src, caption, summary and details.

{% include components/gc-complex-img.html
	 alt="A long description can be found after the image."
	 file=""
	 caption=""
	 summary=""
	 content=""
%}

or

{% include components/gc-complex-img.html
	 alt="A long description can be found after the image."
	 src=""
	 caption=""
	 summary=""
	 details=""
%}
