+# E-commerce Product Images
+
+## Resolution and Framing
+
+- Minimum working baseline: **1000 × 1000 px**
+- Better zoom-safe default: **2000 × 2000 px**
+- Main catalog images often want **1:1**
+- Small products and detail shots usually need more source resolution, not more sharpening
+
+## Background and Edge Quality
+
+- Main marketplace image often needs pure white or near-pure-white background.
+- Product fill commonly should sit around **85-95%** of the frame for major marketplaces.
+- Edges must be clean: no halos, dirty masks, or fringing.
+- If shadows are allowed, keep them subtle and consistent across the catalog.
+- Keep enough padding that the product does not feel cramped after marketplace cropping or thumbnail rounding.
+
+## Color and Consistency
+
+- Use sRGB for marketplace delivery.
+- Do not auto-enhance product color without validating against the real item.
+- Keep crop margins, lighting direction, and white balance consistent across the set.
+- Catalog inconsistency makes the whole store feel lower quality even when each image is individually acceptable.
+- Variant images should preserve a consistent camera angle and scale unless the marketplace expects a different shot type.
+- If background removal is used, inspect edges around hair, glass, reflective metal, and fabric fringing at 100%.
+
+## Marketplace Rules
+
+| Platform | Typical baseline |
+|----------|------------------|
+| Amazon | White main image, square-safe, zoom-friendly |
+| Shopify | Flexible background, but consistency matters |
+| Etsy | Stronger lifestyle freedom, but thumbnails still need clarity |
+| Walmart | White-background expectations are stricter |
+
+- Marketplace uploaders normalize aggressively; validate the processed result after upload when it matters.
+- Some catalogs require the main image to be cleaner and stricter than secondary lifestyle images; do not apply one styling rule to both.
+- If a store theme renders product cards larger than the uploaded image can support, the fix is usually source dimensions and theme sizing together, not more sharpening alone.
+
+## Product-Image Traps
+
+- Product too small in frame
+- Background not truly white where required
+- Detail lost because the source was over-compressed
+- Variant images cropped inconsistently
+- Reflection, shadow, or mask style changing from product to product
+- Text overlays or badges that are not allowed on main images
+- Cutout edges that look fine zoomed out but fail at zoom or marketplace moderation
+- Uploading already heavily compressed files and then letting the marketplace compress them again
+
+## Quality Checklist
+
+```
+□ Product fills the frame appropriately
+□ White-background requirement checked
+□ Edge cleanup verified at 100%
+□ Zoom/detail still holds up
+□ Catalog crop and lighting look consistent
+□ Metadata/privacy decision made
+```
