How many pictures can I list per item using the Storefront templates?
For Enhanced, Professional and Enterprise tiers, two images are supported and are referenced by 2 separate fields in the product configuration screen. If you have more than two photos, you could incorporate HTML links to additional images as part of the product description (see Brief Description and/or Description fields). Those images could be stored locally in the database as part of your product catalog or they could be stored outside of the Storefront hosting environment and dynamically pulled into the product detail template as a shopper navigates to the product.
