Walmart Marketplace rule
Walmart: 1,000px floor, 2,200px recommended for the hero image
Walmart recommends the hero (primary) image at 2,200×2,200 px and treats 1,000 px per side as the practical quality floor; 1,500 px is the minimum for zoom-on-hover, and primary images under 500×500 px are automatically unpublished.

What we check
CatalogPrep reads image dimensions and flags hero images below the 1,000 px floor on either side; 2,200 px is surfaced as a recommendation for zoom quality, not a hard requirement. Below 500 px Walmart auto-unpublishes the listing.
How to fix
Re-export from your camera or design source at higher resolution. CatalogPrep does not upscale beyond source pixels to preserve quality.
