The “Primary Image Missing” error suggests that Walmart cannot locate your primary image. Please check the URL of your products to ensure that it directly links to the image file and not to a preview page. If you are hosting the image on Dropbox or your website, this issue can occur. Additionally, ensure you are not providing links to images hosted on prohibited servers like Amazon.
Furthermore, it is essential to review the Guidelines & Requirements for Product Listing Images provided by Walmart. These guidelines outline the specific criteria and standards for images used in product listings. Adhering to these guidelines will help ensure that your images meet the requirements.
If you have verified the URL and confirmed that it meets the requirements, try resubmitting the item with a valid primary image. Sometimes, this error may appear even when the image was initially submitted correctly. If resubmitting the product does not resolve the issue, please open a support case with the Walmart support team for further assistance.
