How Bulk Assign Variant Images Works
The Bulk Assign feature in Rubik Variant Images & Swatch allows you to assign variant images to hundreds of products automatically, as long as your product images follow a consistent grouping structure.


Bulk Assign analyzes the order of your product images inside Shopify and automatically groups them based on the option you select, such as Color. It assigns each group of images to the correct variant across all selected products.
To work correctly, your product media must follow this structure:
- All images must be arranged in sequential groups by variant
- Each group must begin with that variant’s Shopify assigned featured image
Example:
Black (variant image) → Black → Black → Black
Orange (variant image) → Orange → Orange
Green (variant image) → Green → Green → Green
Rubik detects each variant featured image and collects all images that follow it until the next variant featured image appears. This allows the system to automatically identify image groups with high accuracy. If your product media follows this exact order, Bulk Assign will correctly assign variant images across multiple products.
Step-by-Step Guide
Step 1: Select an Example Product
Choose a product that already has properly grouped images in Shopify media.
Rubik will use this product as a reference to understand your image structure.
Example structure:
- Orange (variant image)
- Orange
- Orange
- Black (variant image)
- Black
- Black
- Green (variant image)
- Green
- Green
The first image of each group must be the official variant image assigned in Shopify.
Step 2: Choose the Option That Controls Image Changes
Select the variant option that determines which images should change. For most products, this is the Color option, but any option that defines visual differences can be selected.
Example values:
- Orange
- Black
- Green
Step 3: Preview the Result
Rubik will show a preview of how it detects each variant group based on your image order. If the preview looks incorrect, you must reorganize your images in Shopify media before continuing.
Step 4: Bulk Assign to All Products
Once the preview is correct:
- Choose which products you want to update
- All products
- Selected products
- Start the Bulk Assign process
- Rubik will assign images in the background
- All selected products will automatically receive their correct variant images
