We’re wrapping up our ChatGPT-4o image series with one of the most useful applications - a visual ad builder that actually stops the social scroll.

You’ve seen how GPT-4o handles product visuals, infographics & explainers. Now it’s time to turn that image power toward sales, launches & promos.

Describe what you want to promote, and GPT-4o will generate polished, on-brand images tailored for wherever your audience scrolls. It’s ideal for lean teams, scrappy marketers & anyone who needs great visuals fast.

Before you dive into the steps below, here’s the flow to keep in mind:

You’ll combine everything you gather—your product photo, inspiration image, style notes, layout preferences—into one complete initial prompt. That way, GPT-4o has the full picture from the start.

After generating your first image, you can use quick follow-up prompts to tweak anything that needs adjusting, like placement, background color, or font style.

Now let’s build it.

Step 1: Open a GPT-4o chat or click ‘Create image’

You can type a fresh prompt or just click the ‘Create image’ button to get started.

Step 2: Describe the layout & tone—not the platform

Avoid phrases like “Facebook ad” or “LinkedIn post”—GPT-4o may create an ad about those platforms. Instead, focus on how the image should look or feel.

✅ Try: ‘Make this clean and professional for a feed post’

✅ Try: ‘Format this for a vertical video-style layout’

Step 3: Upload those reference images

Want your visual to match your brand or a particular style you like? Drop in a product photo—or any inspiration images you gathered as references.

GPT-4o will use them to match colors, layout, and style more accurately.*

Step 4: Choose the right aspect ratio

Say: ‘Make this vertical (9:16)’ or ‘Format this in a 4:3 aspect ratio’

Step 5: Refine with small prompt tweaks

If the font feels off or the layout’s awkward, don’t start over—just prompt for edits.

Step 6: Download and polish

Save your image and open it in Canva if you want to resize, sharpen the text, or create a series.

‘Create a [descriptive, brand-focused] promotional ad image for [product/service] using the attached [product photo / inspiration ad / brand assets] as visual references. Base the layout, style, and overall vibe on these references, but adjust to match [specific brand notes, like colors, fonts, tone]. Use “[headline text]” as the headline. Apply a [background style], [font style], and [tone or mood] that fits the brand feel. Format it for a [4:3 or 9:16] layout for social media.’

Example:

‘Create a clean, modern promotional ad image for an online AI tool directory, Futurepedia, using the attached logo and inspiration ad as references. Match the layout and style, but adjust the colors to navy blue and sky blue, and use a bold sans serif font. Headline: “Discover AI Tools That Work For You.” Use a similar background that feels innovative but approachable. Format it for a 16:9 layout for social media or web banners.’

Then, prompt GPT-4o to follow the style of your inspiration—but adapt it for your brand. Tell it what to tweak:

Better references + brand-specific prompts = sharper first drafts and less editing later.

Don’t stop at just one version. Use the same concept to generate 3–5 image variations—changing headlines, layouts or color schemes slightly.

Post them as a carousel on Instagram, TikTok, or LinkedIn to drive more swipes, saves, and clicks.

Avoid naming platforms like “Facebook” or “LinkedIn” in your prompt—GPT may misread your intent

Text may render a bit soft—try using Canva to overlay sharper font

GPT-4o doesn’t always repeat itself—regenerating a prompt can often give very different results
