A background swap is an image to image job. Text to image will invent a new SKU.
Upload the pack. Prompt the set. Keep the label.
Why does text to image fail a background swap?
It has no pixels of your bottle, so it guesses a similar product.
Image to image starts from your upload. That is the listing-safe path on this AI image generator.
What prompt should ride along with the upload?
Name only the new set: seamless #f5f5f4, soft shadow, no extra props.
If you also say “luxury perfume campaign,” the model may restyle the bottle.
When do you still use text to image?
For a lifestyle scene you will composite the real SKU into later.
Keep those stills on a separate credit from the swap loop.
How many credits per SKU background?
Usually one; two if you correct shadow. 5 free credits cover a few SKUs; Basic is $1/month for 10.
Expect 30 seconds–2 minutes. Paid plans add watermark-free HD for the PDP.
Start in text to image or image to image, pick a model such as GPT-4o image, then check pricing from $1/month and how credits work before a long run.
