Error 8042 — Image resolution below threshold

Images are below Amazon's recommended 1000×1000 minimum for zoom function. Listing serves but won't show the magnifier on detail pages.

Older catalogs with photography under 1000 pixels, or CDNs serving thumbnails as the main image URL.

1. Source images at 1000×1000 minimum, ideally 2000×2000.
2. Check that CDN URLs aren't serving cropped/scaled-down variants.
3. Re-upload affected SKUs through Seller Central.

• Shopify's default 800×800 not meeting Amazon's threshold
