Config Product Group Media

By default, most Shopify themes only support media display based on a single option (usually Color).

Vetro supports multiple combined options (e.g. Color + Size) with a simple setup:

• No image alt text required

• No SEO impact

• Fully compatible with all store languages (no reconfiguration needed)

Unlike other solutions that require complex metafield setup for each variant, Vetro keeps everything clean, simple, and easy to manage.

1. Create the metafield

Go to Settings → Metafields and metaobjects → Metafield definitions → Products → Add definition

Set up the metafield as follows:

• Name: Product group media

• Namespace and key (Required): theme.group_media_obj

• Type: JSON then Save.

2. Theme Configuration

Step 1: Configuration template

Go to Theme Customize → Products → only_config_group_media

• Click Preview → Change product to the product you want to configure

• Tick the checkbox(es) of the variant option(s) you want to group media

Step 2: Assign media to option values

For each image / video, choose one of the following values:

• Specific variant value
  Example: Alabaster, Dark Olive, 20*20, 12*21 → Media shows only when that variant is selected

• None → Media does not show for any variant

• * → Media shows for all values of the selected option
  Example:
  Option = Color → * → Alabaster, Dark Olive… all display this media

Step 3: Copy and apply the code to the product

• Click COPY CODE

• Click the Edit (pencil) icon of the configured product

• Scroll down to the Product group media metafield

• Paste the copied code → Save

FAQ

1. Why don’t “Pick first variant” or “Pick first variant available” show the correct first variant image?

You will follow option is enabled: Product page → Media → Show first media

When enabled, the theme always displays the first product media, regardless of the selected variant. So you will disable Show first media to display the correct variant image.

2. How many options can I combine?

You can combine up to 3 options (e.g. Color – Size – Fabric).

This is due to Shopify’s limitation:

• Maximum 3 product options

• Maximum 2,048 variants per product

As a result, Product Group Media can only be configured within these limits.

3. Where does Product Group Media work?

Besides the product page, Product Group Media also works on:

• Quick view

• Featured product section
