What method is used to display uploaded images on the Storefront, besides content assets?

The method used to display uploaded images on the Storefront, besides content assets, is ISML templates. ISML (Interactivity Server Markup Language) is the templating language used in Salesforce B2C Commerce, allowing developers to create dynamic web pages by embedding JavaScript logic into HTML-like syntax. This flexibility enables the incorporation of various assets, including images, effectively pulling them into the Storefront's interface directly from the backend.

ISML templates can reference images stored in content assets and adjust their presentation based on different contexts or user interactions, making them essential for delivering a customized user experience. While content slots can also display content and are useful for layout management, they rely on ISML templates to render the content in the appropriate view on the storefront.

The other options do not serve the purpose of directly displaying uploaded images. Payment types are related to transaction processing, storefront catalogs focus on product offerings, and content slots serve a different role in managing how content is organized and presented, rather than directly dealing with the display of images.
