Make on-brand carousel images with your ChatGPT plan
Every illustration in my carousels came from gpt-image-2 on my regular ChatGPT subscription. No API key, no extra bill.
Where to run it
The simplest place is ChatGPT itself: ask it to create an image. I run mine from my AI bot app, which signs in with the same ChatGPT account, so it can make them in batches.
The style prompt
Write this once and put it in front of every image request:
Editorial illustration for an Instagram carousel. Flat bold shapes with subtle grain and paper texture. Palette only: [your background hex], [your accent hex], [your dark hex], plus one soft neutral. Friendly, clever, uncluttered, strong silhouette readable on a phone. No robots and no brain shapes; any humans are faceless or shown only as hands or silhouettes. No brand logos. No words, letters or numbers anywhere in the image unless the scene names them exactly. Wide landscape composition with the main subject centered.
Then add one line: "Scene: [what happens in this image]".
Rules that kept 45 images consistent
Hex codes, not color names. "Orange" drifts; #C05F3C doesn't.
Ban words in the image. AI still garbles text. Put your headline on the slide, not in the picture.
Leave room for the headline. Say where the subject should sit.
No real people's faces. Robots, hands and silhouettes keep it yours.
What it took
About 30 seconds per image, three at a time, 45 images. Nothing extra beyond the plan.
