Change Thumbnail Image Size

[JoeyRoo]

Looking for a way to adjust the thumbnail image sizes on the left. Also is there a way to only show the images of the color variant selected and not all the images?

Go to your online store → edit code → product-thumbnails.css and paste this code there in the end of file

.product-image-container.product-image-container--thumbnails .product-thumbnail-container .product-thumbnail {
    width: 80px !important;
}

Adjust the pixels as per need

This works when adjusting the size, but then the images get hidden underneath the main image. See image attached as example
