Pick "Blue" and see the blue photos. This module maps the images a product already has to the option values that product already offers, so choosing an option swaps the main image and the thumbnail strip to the matching set. Mapping is done per product from one admin screen: search the product, then tick which of its existing images belong to each option value — no re-uploading and no duplicate products. On the storefront the swap is pure JavaScript against the gallery that is already on the page, and it is deliberately conservative: an option value with no mapping leaves the gallery exactly as OpenCart rendered it, and the original images are restored when the shopper clears the selection. Built for the stock OpenCart 4.1 product template, with the gallery selectors exposed as settings so a custom theme can be pointed at its own markup.
