This exemplifies the following parameters:
title: analogous to the \Htitle argument. Shows up preeminently, and sets a default ID if one is not given. It is recommended that you don't add a period . to it, as that would show in cross references
description: similar to title, but allow for further explanations without them appearing in cross references to the image
source: a standardized way to credit an image by linking to a URL that contains further image metadata
