A main-image (or early-gallery) technique that visually demonstrates a product's contrasting or dual-use capability — e.g., a bottle shown holding both a hot and a cold drink — rather than stating the capability as text or a spec (such as '20 KPA suction power', which shoppers rarely search for and can't evaluate at a glance). Showing beats telling: a shopper scanning search results processes a picture of the feature in use faster than they would a caption.
Apply: identify the product's most contrasting or surprising capability, stage a single image that shows both states/uses at once, and reserve spec numbers for places shoppers already expect them (bullets, A+ modules) rather than the image itself.
Selection should still pass the Two-Question Feature Filter before it earns space in the image. Related image types: Before-and-After Results Image, and the broader Product Photo Pain-Point/Solution Strategy.
