Looking to add an extra level of interactivity to your product pages? With a variant select feature that uses thumbnail images, you can give your customers a unique browsing experience - and the good news is, it's not as complicated as it may seem!

While there are plenty of video tutorials available online, they often don't work with newer Shopify themes like Dawn 5.0. And while some may suggest downloading an external app, that's not always necessary either. With a simple code snippet, you can implement the thumbnail image variant select feature yourself.

In addition to the basic functionality, I've added a feature that allows for the selection of multiple variant images using the image alt feature. While assigning alt tags to multiple images can be time-consuming, it's a straightforward process if you already have a CSV file for your product.

Please note that this feature won't work with apps that change the product options. Additionally, for products with several options, always make sure to put the variant to select first in the variant selection. This will make it easier for the code to respond to the selected image, especially since an image can be used several times in the options. Before you begin, make sure to uncheck the "Hide other variants' media after selecting a variant" option in your theme editor, and use either the "thumbnail carousel" or "thumbnails" option. Additionally, make sure to assign an image to every variant option and use the image alt tag. If you're already using image alt tags for SEO purposes, contact us to discuss other options.

5. If you have multiple images in a variant option, you need to add the code below next to the "<media-gallery." Please check the image for placement. Click SAVE.



For Dawn below 8.0 version, you have to open the main-product.liquid under the Asset folder:

Hi @Jasmin,

I understand your concern. I hope you read the use of alt tag explained in this page prior to purchase (images provided as well). Unfortunately, to keep the code still a non-developer friendly, we need to utilize the alt tag to call from the backend. We can however add some code to show different tag for image and different tag for SEO. Another way is to upload the images as a variant metafield but this will require more work. You can contact me for this issue using Chat with us.


Hey there, I purchased your code snippet and it is great in it’s own right! However, my concern is that it is using alt tag which should be reserved for SEO. Do you have a code snippet that uses that image linked to the variant?

Thanks in advance
