Using AI Image Generation for Marketing: Prompts That Actually Work

How to use AI image generation for posts, ads and mood boards: prompt structure, keeping brand tone, and cautions on rights and misleading images.

The marketing team of a small coffee shop has to make a promotional post for a new menu item every week, without the budget for a photographer each time. They try AI image generation and get a beautiful coffee cup that looks like an overseas ad, but nothing like their own shop. The colours are off-brand, and customers might think the real drink looks like that. This is where many people stumble when they start using AI images.

What is AI image generation, and what work suits it?

AI image generation uses models that create new images from a text description called a prompt. Some tools also accept reference images or let you edit only part of an image. Marketing work that suits it:

• Mood boards and early ideas before briefing a photographer or designer
• Illustrations for articles or posts that show a concept, not a real product
• Backgrounds and elements to combine with real product photos
• Testing several ad directions to see which looks promising before real production

Do not use AI images in place of the real thing for product photos customers rely on to buy, before-and-after service images, or images claiming to show real events.

A prompt structure for marketing work

A good prompt says what you want, in what atmosphere, and where it will be used. Try this structure:

1. Subject: what is in the image, such as an iced latte on a wooden table
2. Setting: place and time, such as a café with natural morning light
3. Style: visual approach, such as minimal photography in warm tones
4. Composition: camera angle and empty space, such as slightly high angle with space on the right for text
5. Format: aspect ratio for the channel, such as vertical for Stories

Example: “Photo of an iced latte on a light wooden table in a café with natural morning light, minimal style, cream and brown tones, slightly high angle, empty space on the right for text, vertical format.” Many tools follow English prompts more accurately, so if results miss, try writing in English.

Keep every image on brand

Create a shared brand prompt

Write a reusable style description covering colour, light and mood, and keep it in a document the team shares. Everyone's images will then look like one family.

Use reference images you have rights to

If the tool accepts reference images, use your own brand images or ones you are licensed to use. Do not copy other artists' work as a reference without permission.

Add text and logos afterwards

Thai text generated inside AI images is often garbled. Generate a clean image, then add text, logo and price in a design tool for better quality control.

Cautions

• Do not mislead customers. Menu or product images far better than reality create disappointment and lose trust.
• Check commercial-use terms for each tool, since usage rights differ. For client work or large campaigns, consult an intellectual property professional.
• Be careful with people. Do not create images resembling real public figures or implying a real person endorses your product.
• Check details every time. Hands, lettering, logos and distorted objects often slip through to live posts.
• Disclose when required. Some platforms require AI-generated content to be labelled; check before running ads.

Use AI to explore visuals faster, but images customers use to decide what to buy must be real.

Where to start

1. Pick one type of work you do often, such as article illustrations or promo post backgrounds.
2. Write a prompt using the five-part structure and generate several versions to compare.
3. Choose the one closest to your brand and turn the words that worked into a shared team prompt.
4. Add text and logo in a design tool and have a second person check before posting.
5. Track post results against your old images to see whether it is really worth it.
