Main image and additional images
For the main image, Walmart asks for:
- A seamless white background. Images of larger items may show the item in an expected environment.
- The item cropped as close to the frame as possible, without excess background. Don't resize a small image to fill the space; it lowers quality.
- No watermarks, seller name or logo.
- No accessories that aren't included, and not too many props.
For every image:
- Match the product name, the product type and the key attributes in the name.
- Show the product or its features. Images saying the product is out of stock or sold out are prohibited.
- No duplicate images on the item page.
- In focus and professionally lit.
- No claims or promotional language about the item.
- No Walmart or other retailer or ecommerce platform logos or names.
- English only.
- Swatch images where they apply.
- If images aren't ready, use only Walmart's designated placeholder. The item won't publish until a real product image replaces it.
Some categories have extra requirements, listed in Walmart's content standards.
