use of gifs / images

The two biggest pngs + the two biggest gifs totalled 1.7MB out of 3MB total for downloading the dwyl/learn-elm-architecture page. They definitely have advantages, but maybe consider

a) Linking to images
b) Linking to two different pages in a `doc` folder with or without images as the viewer prefers (I read github on mobile data a lot)

Start by inspecting the dwyl/learn-elm-architecture page and identifying the two largest PNGs and GIFs that account for most of its download size. Review the proposed linked-image and alternate-doc-page approaches, then confirm the chosen approach reduces the page's asset weight while preserving access to the images.
