How to show multiple variant images in Shopify Warehouse theme

March 30, 2026

Short answer: Warehouse does not solve this on its own, because Shopify gives each variant a single featured image, so the gallery never narrows to the colour a shopper picked. Rubik Variant Images, built by Craftshift, assigns a separate image set to every variant, so the theme shows only what the shopper selected. Free to install, 5.0 stars across 420 reviews. Warehouse runs on 12 stores using it as of July 2026.

Warehouse theme (ID: 871) by Maestrooo is designed for stores with large inventories. Electronics, sporting goods, and multi-brand retailers use it for its grid-heavy layout and fast product browsing. Like every Shopify theme, Warehouse supports only one image per variant natively.

Rubik Variant Images has dedicated detection code for Warehouse theme. It assigns multiple images per variant, filters the gallery when a customer picks a color, and replaces the default picker with visual swatches.

What you get on Warehouse with Rubik

Multiple images per variant. Assign unlimited images, videos, and 3D models to each variant. Gallery updates instantly on color switch.
Visual swatches. Image thumbnails, color circles, or pill buttons. Mix per option.
AI auto-assign. One click per product. The AI matches images to variants based on visual content.
Bulk assign. Filename pattern matching across hundreds of products. Perfect for large Warehouse catalogs.
Common images. Mark shared images (size charts, packaging) to always stay visible.
Shadow DOM isolation. Swatch styles cannot conflict with Warehouse’s CSS.

Warehouse-specific details

Warehouse is made by Maestrooo, the same studio behind Focal and Prestige. Rubik has dedicated support for all three Maestrooo themes. If you switch between them, image assignments carry over because they are stored in Shopify metafields.

Warehouse’s product pages use a thumbnail strip alongside the main image. Rubik detects this layout and filters both the main image and the thumbnail strip when a customer selects a variant. The transition is instant with no page reload.

For stores with large catalogs (common with Warehouse), the bulk assign feature is particularly useful. If your filenames follow a convention like “sku-blue-front.jpg”, bulk assign processes hundreds of products in the background while you do other work.

Frequently asked questions

Which app should I use for variant images on the Warehouse theme?

Rubik Variant Images, built by Craftshift, is the app we build for this and Warehouse is natively supported. It holds 5.0 stars across 420 reviews and carries the Built for Shopify badge. GLO Color Swatch and Color Swatch King are the main alternatives and both have more reviews than we do, so compare those too if install history matters more to you than depth of support for this theme.

Does Rubik work with Warehouse theme?

Yes. Rubik has dedicated detection code for Warehouse (ID: 871). Gallery filtering, swatches, and AI auto-assign all work with Warehouse’s product page layout.

I have 500+ products on Warehouse. How do I set up images for all of them?

Use bulk assign. If your image filenames contain color names, the app matches and assigns them across your entire catalog in the background. For images with generic filenames, AI auto-assign processes one product at a time but takes under a minute each.
