Check your photo against Walmart's rules.
Walmart sets rules for the main image that can be measured from the photo: background colour and square format. Drop a photo to see which ones it meets. It runs in your browser; nothing is uploaded.
Choose a marketplace and a photo.
Rules come from each marketplace's own help pages, summarised in the guides (checked 10 October 2026). Size, file size and format are checked as well.
