A main-image tactic for multi-piece or multi-variant products: lay out every included piece, and separately, the top color/style variants, directly within the main image itself — distinct from Multi-Use Call-Out Image, which calls out use cases rather than piece count or variant range.
For products with many included pieces, showing them all reassures shoppers about what they're getting before they click. For products with 10+ color/style variants, showing every single one clutters the image — capping the display at the top 8-10 variants is enough to signal variety without overwhelming the shot.
Apply: If a product ships with multiple parts customers care about, showcase them all in the main image; if it has 10+ variants, show only the top 8-10.
