Multiple image ratio support in Google structured data.

Google now allows you to specify multiple images for structured data types: articles, events, local businesses, music, products, recipes, tv/movies and videos.

They recommend 16×9, 4×3, and 1×1 ratios, Articles are recommended to have a total resolution of 300k pixels while other types 50k pixels.

Articles still have a recommended width of 696px (which is an amp requirement and I assume only for the 16×9 ratio). Events have a recommended width of 1920px and minimum 720px
