The second listing image should follow a category-dependent rule rather than one universal template: for most categories, image two should be an informative infographic or lifestyle-with-callouts image. For supplements and consumables, image two should instead be the Supplement Facts / Nutrition Facts panel, since that information is often the deciding factor for that category's shoppers. Check the product category before defaulting to a generic infographic. Complements Main-Image Tactic Checklist (image one) and Lifestyle Image Eye-Contact Alternation Pattern (later lifestyle images).
Effective infographic-style secondary images pair short graphics/icons with minimal text so a shopper can absorb the point in a few seconds — avoid paragraph-style spec text ('nobody wants to read a big block of text... homework they never asked for'). Prioritize which features get an icon+label by running them through the Two-Question Feature Filter and keyword research, rather than listing every spec. See also Multi-Use Call-Out Image for showing (not stating) a feature.
