Google’s Nano Banana image models have become a favourite for quick, realistic edits, and the new Nano Banana 2 Lite is built for speed. According to launch coverage, it can generate an image in about four seconds and is rolling out across the Gemini app, AI Mode in Search, NotebookLM and Google Photos. For small business owners, that means you can create product photos, festive sale banners and social posts without hiring a designer for every campaign. This guide gives you 30 tested prompt ideas and simple rules for keeping your brand consistent.

The Product Photo Formula
Great product images follow a simple pattern: product + surface + background + lighting + angle + mood. For example: “A glass bottle of cold-pressed juice on a marble counter, soft green background, natural window light, 45-degree angle, fresh and healthy mood.”

How to Keep Your Brand Consistent
- Upload your logo and a brand colour reference with each request.
- Reuse the same “style sentence” in every prompt, for example: “Brand colours teal and cream, clean modern style, rounded fonts.”
- Edit an existing good image rather than generating from scratch each time.
- Keep the text short: 3–6 words work best inside images.
Turning Images Into Video
Once you have a strong product image, you can animate it with Google’s video models (such as Gemini Omni Flash) for a short reel: a slow rotation, falling confetti or steam rising from a drink.
Legal and Ethical Tips
- Only upload product photos you own.
- Avoid other brands’ logos and celebrity faces.
- Do not create fake reviews or testimonials in images.
- Be honest: edited images should still represent the real product accurately.
A Weekly Content Plan Using Nano Banana
Consistency matters more than perfection on social media. Here is a simple weekly plan a small shop can produce in about an hour:
| Day | Post type | Example prompt idea |
|---|---|---|
| Monday | Product spotlight | Product on a clean studio background |
| Tuesday | Tip or how-to | Infographic card with 3 tips |
| Wednesday | Behind the scenes | Illustration of your team at work |
| Thursday | Customer love | Thank-you card design |
| Friday | Offer | Weekend sale banner |
| Saturday | Lifestyle | Product used in a real-life setting |
| Sunday | Community | Poll or question card |
Editing Prompts That Save Time
Instead of generating new images, edit existing ones with short instructions:
- “Replace the background with a soft beige studio wall.”
- “Remove the cable on the left side of the table.”
- “Make the lighting warmer and brighter.”
- “Add a small green plant behind the product.”
- “Change the banner text to ‘Last Day Today’.”
Measuring What Works
Track which images get the most saves, shares and clicks over a month. Keep the top three styles, retire the weakest, and update your style sentence. Over time your prompts become a reliable recipe for posts your audience actually engages with.
