Pinterest holiday 2026: carousel stills from one product photo

For a holiday Carousel, make four 2:3 stills from one product photo: a clean pack shot, a lifestyle scene, a detail close-up and a gift-ready scene. Pinterest's holiday page says visual searches grew three times faster than text search last holiday season, so the pictures carry the work. The Sume Image API can produce all four in one call with n: 4, and you review them before spending anything on video.

The page gives no image sizes for Carousel ads. Check Pinterest's ad specs before final export.

How do I make four cards from one photo?

Call POST /v1/images with your photo in input_references and aspect_ratio: "2:3". Read the model's supported_parameters first (GET /v1/images/models), because a model accepts only the ratios its catalog lists. Use aspect_ratio: "auto" only when you want the result to match the reference shape.

n runs from 1 up to the model's ceiling, which is 4 on Nano Banana 2.1 (read the n descriptor). Each image is billed as a full generation; failed generations are not billed. Results come back as signed Sume URLs (data[].url). Slow settings can return 202, and then you read the job result instead.

{
  "model": "google/nano-banana-2.1",
  "prompt": "Four-card holiday set for this candle: clean pack shot, cosy mantel scene, wax and wick close-up, gift-wrapped on a table. Keep the label exactly as in the reference.",
  "input_references": [{ "type": "image_url", "image_url": { "url": "https://cdn.example.com/candle.jpg" } }],
  "aspect_ratio": "2:3",
  "n": 4
}

What should I check before upload?

Check labels and text. Image models can alter small print, so compare each card with the original photo at full size. Keep one subject per card and put the offer in the Pin text, not in the picture, so you can change it without a re-render.

If a card should move, animate that one still with the video API using frame_images. The image step is the cheap place to find out what works.

What should I keep consistent across the stills?

A carousel reads as one set when the cards share a few things.

• The same product colour on every card.
• One background family, such as cream or deep green.
• The same crop ratio on all cards.
• A short caption that does not repeat the title.
