Why doesn’t the product image change when I click a variant?

Our app works based on Shopify’s native variant configuration. For the variant image to change correctly, your theme’s variant picker must be enabled.

How to check and enable it:

Go to Online Store → Themes → Edit theme

Online Store Themes section with the Edit theme button

Open the Product template

Product template selected in the theme editor

In the Product information section:

Add the theme’s Variant Picker
Add the OPTIS app block as well

Adding the OPTIS app block to the product template

👉 Important notes:

OPTIS restyles and enhances Shopify variants - it does not create a separate variant system.
The theme’s variant picker must remain enabled for image switching to work properly.
If you see both the theme variants and OPTIS swatches showing at the same time, this is usually a theme conflict. In that case, please contact our support team and we’ll help resolve it.

After enabling the variant picker, kindly double-check the product page. If the issue still persists, feel free to reach out - we’re happy to assist further.
