Normally, variants are selected from a drop-down menu, however, customers tend to go through product images to find the variant they like, without making a selection from a dropdown. Once they add a product to cart, the initially selected variant will be added, instead of the image that they chose.
In order to improve user experience, you might want your customers to be able to select a product variant by clicking a variant image, and we can help you with that.
* This feature is recommended if you have 1 image per variant. If you have multiple images per variants, you can take a look at Display thumbnails connected to the selected variant task.
** We might need an additional task to make it work on mobile (swiping through images), depending on the theme.
