What it means
Product images need to be accessible and meet the requirements for the relevant product category and destination.
How to fix it yourself
- Open the exact image URL and confirm that it loads without authentication or an expiring session URL.
- Check that the image represents the product, is large and clear enough, and avoids promotional overlays where prohibited.
- Update the image URL in the source catalogue or feed and ensure image-host security does not block Google's crawler.
- Wait for the image to be fetched again and review the item diagnostics.
