A computing system comprising a server having a processor and a memory, the computing system programmed with executable program code to perform a process that comprises:

• generating an interactive electronic catalog page that includes an image of a physical product;
• maintaining, in computer storage, image mapping data that maps particular regions of the image to respective component identifiers of components of the physical product, each of the components being separately reviewable by electronic catalog users;
• in response to user interaction with the electronic catalog page on a user device, updating a display of the electronic catalog page to include a plurality of region identifiers on the image, each region identifier identifying a respective one of the particular regions of the image, each region being individually selectable on the electronic catalog page to select the corresponding, separately reviewable component of the physical product;
• detecting a user selection, on the interactive electronic catalog page, of one of the particular regions of the image;
• determining, from the image mapping data, a component identifier corresponding to the selected region of the image, said component identifier identifying a component selected by the user;
• updating a display of the interactive electronic catalog page with a display of user-submitted reviews that are specific to the selected component;
• and
• providing a user option, in connection with the selection of the component, to submit a review that is specific to the selected component.
