GO Product Page + Zoom allows you to automatically change to the corresponding swatch (product options) by clicking on the variant images.
How to link
On an individual product basis
On the product page, scroll down until you see Tags on the right hand-side. Then, simply add vw-variant-vi-link as a tag
Globally on all products
On the app’s home page, simply click on App Preferences, located at the bottom left corner. Then, enable Link variant image to product option (swatch) by ticking the checkbox. Then, click Close on the bottom right of dialog, followed by the Save button on the top right of the app.
How to assign multiple variant images to each variant while using this feature
On Variant Wizard, first assign all the images you want to link to the corresponding variants within the variant rows. Once completed, click on the 3 dots button located at the top right corner of the page and then turn the Variant Images toggle to the off position, as shown in the screenshot below.
The app will then revert the product to using the standard product image gallery layout (where all images are shown), and clicking each image will change to the correct corresponding product option (swatch).
