Buyers judge your product in 50 milliseconds — before they read a single word.
The white background rule
Marketplaces prefer clean white backgrounds for hero images, and buyers subconsciously read them as "professional store" rather than "reseller".
Resolution matters
1600×1600 is the sweet spot: it qualifies for zoom on eBay and stays under upload limits.
Lifestyle images sell the outcome
Your second and third images should show the product in use. AI-generated lifestyle scenes now perform within a few percent of studio photography at a fraction of the cost.
Consistency compounds
When every listing in your store shares the same image style, buyers trust the store more — and store trust lifts every listing's conversion.
