"Grouped variant images". Solution good for all themes, no change to markup required.

multiple images for a variant.md

What to do

1. Use the alt text to associate the additional images - besides the variant image - to the option value. Example: say you have 3 images that show the Blue variants, then a) associate the first image as variant image to all Blue variants, and b) set the alt text of the 2 additional images to 'Blue'.
2. Copy+paste the code found in the product.liquid snippet below at the bottom of your product.liquid template.

How that works, essentially

Only the images associated to the currently selected variant are shown. Other images are hidden.

What to expect, the specifics

1. On page load, only the images associated to the selected variant will be shown.
2. When a new variant is selected, only the images associated to that new variant will be shown.
3. The wrapper of the image, if one is used, is hidden, so there will be no left-over border shown on the page when an image is hidden.

Requirement

jQuery 1.7 or later.

product.liquid

{% assign option_name = 'Color' %}

{% if product.options contains option_name %}

<script>

// Grabbing product thumbnails
// Covers: Editions, Launchpad Star, Lookbook, Kickstand, Startup, Simple, Radiance, Minimal, Supply, New Standard and many more.
var thumbnails = jQuery('img[src*="/products/"]') /* All product images */
  .not('#related-products img')                   /* Except related products, thumbnails not clickable */
  .not('a[href^="/collections/"] img')            /* Except related products */
  .not('a[href^="/products/"] img')               /* Except mini-cart products */
  .not('header img')                              /* Except mini-cart products, thumbnails not clickable */
  .not('#drawer img')                             /* Except mini-cart products, thumbnails not clickable, in Simple theme. */
  .not(':first');                                 /* Except first one, i.e the main image */
  
var optionSelect; 

{% assign option_index = 0 %}  
{% for option in product.options %}
  {% if option == option_name %}
    {% assign option_index = forloop.index0 %}  
  {% endif %}
{% endfor %}
  
{% if product.options.size == 1 %}
  optionSelect = '.single-option-selector';
{% else %}
  optionSelect = 'label:contains({{ option_name }}) + .single-option-selector';   
{% endif %}
  
jQuery('form[action="/cart/add"]').on('change', optionSelect, function() {
  var optionValue = $(this).val();
  thumbnails.each(function() {
    var wrapper = $(this);
    while ( wrapper.parent().children().length === 1 ) {
      wrapper = wrapper.parent();
    }
    if ( jQuery(this).attr('alt') === optionValue ) {
      wrapper.show();
    }
    else {
      wrapper.hide();
    }
  });
});    
</script>

{% endif %}

Same to you @DonnaRx, any luck solving for products/variants with more than one option? Thanks!

@GoInterstellar @tdmGitHub @DonnaRx i have a solution for 3 options, but it has a different approach using filenames and grouping by classes.

The code is somewhat working on the Debut theme, the only problem I am having is that when you first select the product that has many variants, all variant photo show for the initial product, after picking a specific color, then it will only show the pictures related to that color. Is there a way to not show all the pictures at first?

@GoInterstellar (& @DonnaRx and @tdmGitHub) did you have any luck with the multi-selector option?

Hello, I can't seem to get this working in Slate. Is there something I could be missing in the Slate framework?

Hi Caroline:

I added the above code to Shopify theme - Brooklyn, Minimal, Debut, and they all work. However, when I add the above code to boundless theme, I wasn't able to get the product page to show image only related to color variant.

Any suggestion? Please help. Thank you.

I am using the Handy theme. Please help implement this! Do I just add above code to my product.liquid file?

Hi Caroline:

Can you please tell me how it is work with swatches in debut theme? One more thing i have many images for 1 variants so i want to show all images when i select the color swatch.

Please reply fast.

Thank you

Hi, please I need a code to automate ALT text to generate as Product Title. I use the Turbo theme. I can't seem to find where to change the image.alt to product.title. Thanks for your help.

@GoInterstellar @tdmGitHub @DonnaRx i have a solution for 3 options, but it has a different approach using filenames and grouping by classes.

Hi can you please share this solution? It would be massively helpful

I'm having trouble getting this working on the current Debut theme (V17). I've pasted this code into the product.liquid file and modified the alt tags to match the color variants I'm using, but the product page still loads all the images instead of the images for each variant (Alt tag). Any ideas?

Hello, is someone found a solution to remove the white space?
