Reply To: variation selection change does not update the main product picture

To anyone who has this issue, here is a temporary quick fix. Note that the image displayed is using jpeg rather than webp for this one product display image. But it’s just one image, I don’t have time to dig this further.

Put this code into the product/post page, I am using this plugin, pick the post tab https://wordpress.org/plugins/header-footer/

Then insert this code

<script>
jQuery( document ).ready(function() {
	jQuery('.product-image-wrap source').addClass('wp-post-image wp-post-image');
}); 
</script>
