How to Create Marketing Images With AI: Prompts and Edits

Every ad, social post, landing page update, and seasonal campaign needs its own artwork, and the volume adds up long before the budget does. AI image generation closes most of that gap — not by replacing a designer on the work that matters, but by handling the twenty variations nobody was ever going to commission individually.

The catch is that a vague prompt produces a vague image. “Make a marketing image for our coffee brand” returns something generic, and the second attempt returns something generic in a different style. What follows is a routine that fixes both problems: one detailed brief up front, then follow-up edits instead of fresh starts.

Create a marketing image in three steps

Step 1. Decide what the image has to do

Before you open the prompt box, answer three questions: where the image will appear, what it needs the viewer to understand in the first second, and what has to stay consistent with your existing work.

That last question is the one people skip, and it is the reason AI image sets look like they came from five different companies. Write down your two or three brand colors as hex values, the general mood (warm and hand-made, clean and technical, bright and playful), and the aspect ratio the placement actually needs.

If you are not sure what the image should show yet, start in chat rather than in the image tool:

Step 2. Write the prompt like a brief, not a wish

A usable image prompt names the subject, the setting, the lighting, the composition, the color direction, and the format. Skip any one of those and the model picks for you.

Two details in there do most of the work. “Room at the top third for a headline” means you get an image you can actually lay type over instead of one you have to crop. “No text” matters because generated lettering is still the least reliable part of most image models — add real type afterwards in whatever tool you already use.

Step 3. Refine with follow-ups instead of starting over

When something is close but wrong, describe the change rather than rewriting the whole brief. Most of the time the composition you liked survives and only the detail you named moves.

This is also where you generate the rest of the set. Once one image is right, ask for the same scene in the other formats you need — a 4:5 for the feed, a wide crop for the site banner, a vertical for stories — so the campaign holds together across placements.

Three habits that raise the hit rate

Write specific prompts, not adjectives

“Professional,” “modern,” and “eye-catching” describe a reaction, not an image. Replace each one with something a photographer could act on: a lens, a light source, a surface, a color. “Modern” becomes “flat lay on seamless white, hard overhead light, single accent color.” The more the prompt reads like a shot list, the less the model has to guess.

Keep a house style you reuse

Save the sentence that describes your look — palette, lighting, framing, level of realism — and paste it into every image prompt. This one habit is the difference between a coherent brand feed and a collection of unrelated pictures, and it costs nothing to maintain.

Keep one message per image

An image that tries to show the product, the discount, the season, and the lifestyle communicates none of them. Decide which single idea the image carries and let the caption or the headline do the rest.

Where this fits in ChatUp

ChatUp’s Image Gen tool generates from a text prompt and can use uploaded reference photos when the selected image model supports them. Animate Photo turns a still into a short clip. Review both outputs against the real product and each platform’s disclosure rules.

Because generation sits in the same app as chat, the concepting step and the production step do not live in different tools. You can brainstorm directions with a model and hand the winning description into an image prompt. Keep the reviewed house-style sentence in the current conversation or paste it into a new one.

Frequently asked questions

Can AI generate images with text on them?

Sometimes, but not reliably at small sizes or in specific typefaces. Generate the image without text and add real type afterwards — you keep control of the font, the kerning, and the accessibility of the final asset.

How do I keep AI images consistent across a campaign?

Fix the variables. Reuse the same palette, lighting description, framing, and level of realism in every prompt, and generate variations by editing an approved image rather than by writing a new prompt each time.

Can I use AI-generated images in paid ads?

Usually, but check two things: the terms of the tool you generated with, and the advertising policies of the platform you are running on. Some networks require disclosure for synthetic imagery in certain categories, and rules change often enough to be worth rechecking each quarter.

What size should a marketing image be?

Work backwards from the placement rather than generating one size and cropping. Ask for the aspect ratio you need in the prompt, and produce the other ratios as separate variations of the approved image.

Make the first image the template

The value in AI image generation is not the first picture — it is the fortieth, produced in the same style, in a fifth of the time. Spend the effort on one detailed brief, save the part of it that describes your look, and treat every image after that as an edit rather than a fresh roll of the dice.
