The problem

A custom image component may assume a chosen image always exists. Guard the value before requesting an image URL and provide an intentional text fallback.

Placement and precautions

Duplicate the theme and work in its unpublished preview. Save the original files and change one component at a time.

Use inside a product context for a simple image component. Merge the fallback translation. Preserve the responsive sizing and loading priority from your existing image component when integrating this guard.

Bounded Liquid example — not a replacement for an entire theme file:

{% if product.featured_image != blank %}
  {{ product.featured_image | image_url: width: 600 | image_tag }}
{% else %}
  <p>{{ 'vbl_48.fallback' | t }}</p>
{% endif %}

Translation keys: Merge this object into the root of the existing locales/en.default.json, keeping all other keys and valid commas. Add corresponding translations to every active language file. Replace generic example wording with accurate store content. Do not replace the entire locale file.

{
  "vbl_48": {
    "fallback": "Image not available"
  }
}

Check in preview

Preview a product with an image and one without. Check there is no empty src request or misleading stock photograph. Test translated fallback text and layout dimensions.

Limits to understand

This does not fix a network failure for an existing image or implement a media gallery. Loading priority must match placement; the main above-fold image must not become lazy-loaded.

Validation: This code and locale JSON passed Shopify's validation tool. This is static validation, not proof of rendering, accessibility, theme compatibility, indexing or improved sales. No live merchant store was changed or purchase performed.

Rollback

Restore the saved markup and styles if anything regresses. Remove any new calls before deleting their referenced files. Remove only unused locale keys introduced for this example. Keep the previous working theme available until the full affected journey has been checked.
