Common warnings and what to do
| Warning | What it means | What to do |
|---|---|---|
| Too small for zoom | The image may not meet zoom-quality expectations. | Use a larger square source image. |
| Not square | Walmart product images may display poorly or require rework. | Create a 1:1 padded or cropped version. |
| File too large | Upload may fail against file-size limits. | Compress the final JPG or PNG. |
| Manual white-background check | Browser metadata cannot prove background policy compliance. | Review the image visually before upload. |
How to fix image issues after checking
If ListingPic flags size or ratio issues, export a larger square image with the full product centered. Then manually review white background, overlays, borders, and product-only content before upload.
Walmart main images need visual review
Dimensions, format, and file size can be checked automatically. White background, product-only content, text overlays, borders, logos, and category-specific content policy still require a human review against current Walmart Marketplace documentation.
- Use a square high-resolution export.
- Compress final files before upload.
- Review white-background and product-only rules manually.
