The main image displays accessories, props, or extra items that are not part of what the buyer receives. TikTok requires the main image to show only what's actually shipped.
TikTok's listing accuracy rules prohibit lifestyle or bundle imagery in the main slot when the extras are not included in the SKU. Sellers reuse marketing photos that include props (a phone next to a charger when only the charger ships), and the system rejects these to prevent buyer disputes. Bundle images are allowed only if every visible item ships together.
