I don't understand how lazy loading could help here. The images are all behind hyperlinks, and their display sizes are all hardcoded into the HTML. There is nothing preventing the browser from completing the page layout immediately and backfilling the images as the load.

That is not to say the page is well-designed or pretty - it is hideous. But lazy loading would make it strictly worse by adding js parse+eval latency on top of the loading time for the images.
