Before uploading to any AI tool or marketplace, verify your source photo:
Main image (position 1) — before uploading to Seller Central:
Secondary images (positions 2–9):
Technical verification:
- [ ] Opened in image editor and sampled background colour (main image) — reads 255,255,255
- [ ] Verified product fills 85%+ by visually reviewing at full resolution
- [ ] All images are minimum 1,000px × 1,000px

Before uploading to Shopify Admin:
Collection page considerations:
- [ ] Main image has consistent background colour across all products in the collection
- [ ] Product is visible and identifiable at collection thumbnail size

Sellable handles the majority of this checklist automatically. White backgrounds are calibrated to Amazon and Google specifications. Resolution is always 4K. Aspect ratios are consistent. Product fidelity is preserved.
What Sellable doesn't handle (and you should verify manually): - Alt text in Shopify (add after upload) - Amazon secondary image mix (you decide which image types to include) - Google feed attribute alignment (product colour in feed must match image)
For teams managing multiple catalogues or multiple contributors, saving this checklist as a standard operating procedure prevents the errors that cause listing suppressions and poor marketplace performance.
*"We created an SOP around this checklist and Sellable together. Zero Amazon suppressions in the last six months across 280 active ASINs."* — Danielle K., ecommerce operations lead
*"Running a checklist felt like overkill until we got 22 Google Shopping rejections in one feed update. Now we check everything."* — Marcus R., ecommerce marketing manager
*"Sellable handles 80% of this checklist automatically. The 20% that remains takes about 5 minutes per product. Well worth it to avoid suppressions."* — Sophie T., Shopify brand owner
