Quick answer

Nano Banana is the popular name for Google’s Gemini image generation and editing model. For marketing, it is most useful for editing photos you already have: changing backgrounds, creating ad variations and placing products in scenes. Start from a real product photo, describe the change clearly, and check every image for accuracy before it runs.

What it is good at

  • Replacing or cleaning up backgrounds on product photos.
  • Making several ad variations from one image: seasons, settings, colours.
  • Keeping a product or person consistent across a set of images.
  • Combining two images, such as a product and a room.

Prompts that work

  1. 1Start with your photo“Using this product photo, place the bottle on a timber bench in soft morning light. Keep the label exactly as it is.”
  2. 2Ask for variations“Make three versions for a square Instagram ad: summer, winter, and plain studio background.”
  3. 3Edit specifics“Remove the cable on the left. Do not change anything else.”
  4. 4Fit the format“Reframe as 9:16 for a Story, leaving space at the top for text.”

What to check before publishing

  • Labels, logos and text are correct and readable.
  • The product looks like what the customer will receive.
  • No invented features, sizes or packaging.
  • You have rights to any photos you uploaded.

Images made with Google’s models carry an invisible SynthID watermark. Some platforms may label AI-generated images, so avoid using them to show results you cannot deliver.
