Walmart Image Requirements: Complete Photo Guide
Walmart image requirements explained: verified minimum size, Main Image rules, prohibited content, category differences and a practical checklist.
Walmart's published image guidelines combine rules that affect publication with requirements for the Main Image and supporting lifestyle or graphic images.

Walmart Main Image rules
A Main Image is required when an item is created. Images must be at least 500 x 500 px; Walmart states that an item is not published below this minimum. Stock photos are not allowed: the image must show the actual product being sold.
The Main Image must not show accessories that are not included with the item. Watermarks, advertising language, text overlays, coupons and borders are not allowed, and animated images are prohibited.
Placeholder images are temporary only. The item remains unpublished until the placeholder is replaced. Lifestyle and graphic images must be cropped full bleed to a square with no border.
Widely cited Walmart specifications that are not confirmed here
A pure white RGB 255,255,255 Main Image background and specific recommendations such as 2000 x 2000 or 2200 x 2200 px are commonly reported by sellers and tools, but they are not stated in Walmart's published image guidelines cited above. Those pages also do not state a universal 1:1 aspect-ratio requirement, a specific maximum file size or a specific accepted-format list.
Some categories have requirements beyond the general specification. Verify the relevant category directly in Walmart's Content Standards: Overview before publishing.

- Showing accessories in the Main Image that are not included.
