On-brand image prompts, with firm limits

• The ChatGPT desktop app to make the images, and a folder called something like Social Graphics. Working in Claude? It writes the image prompts, and you open the same folder in Codex in ChatGPT to make the pictures. Claude can also build a text-only card on its own (the third prompt).
• Your approved brand board, copied into the folder. The standing instructions file made from it (CLAUDE.md or AGENTS.md) is plain text, which both apps read easily, so copy that in too. If you don’t have a board yet, start with Brand board from your public website.
• Your real logo file, in the folder, for the text-only card and for adding to finished images.
• A design tool for adding your headline and logo: Canva, PowerPoint, or Adobe Express all work.
• Your office’s policy on AI-generated images, if it has one.

Side note: Florida’s 2024 law (s. 106.145, F.S.) requires a disclaimer on certain AI-made political advertisements. Ask your attorney whether it reaches your office’s voter information. Until you have an answer, follow your office’s own labeling policy.

1. Make the folder and copy your approved brand board into it.
2. Open it in the ChatGPT desktop app: open Codex, click Add new project (or press Ctrl+O), and pick the folder. (In Claude: Code tab, then under the message box choose Local and Open folder…. Full walkthrough: Folder projects.)
3. Say the prompt with your topic. In Claude, use the second prompt for image prompts or the third for a text-only card.
4. Open the images from the folder and look at every one up close. Check each against the four rules above. You know what your office’s ballots, envelopes, and voting equipment look like, so anything too close to the real thing will stand out. If in doubt, make a new image.
5. Add your headline and real logo in your design tool. Proofread the headline.
6. Label it if your office’s policy says to, and add the alt text when you post. Most platforms have an alt text field when you upload an image. If you can’t find it, put a short description in the post itself.
7. Keep the folder. The final image and the prompt stay together with the post’s records.

One run of the first and third prompts, with a brand board and logo for a made-up Sample County. Claude can’t draw pictures, so for the first prompt it wrote image prompts.

• A matching series. Ask: “Make five matching graphics for a series on the steps to vote early. Same style, colors, and layout. Only the icon changes.”
• Sometimes the best graphic has no AI image at all. A clean, text-only card in your brand colors (the third prompt) is often clearer. You still read every word and check every fact on it.
• Save the limits once. Put your brand board’s standing instructions file in the folder (see Brand board), so every session follows them.
• Seeing a fake image about your office? See Misinformation response.
• Ready to post? Platform-specific posts covers captions, alt text, and character limits.

About the measured time: “AI’s part” is how long the AI took, start to finish, in a test run of these prompts on September 27, 2026. It works on its own while you do something else. “By hand” and “With AI” are estimates of your own time.

Estimate: the AI makes a few options in a minute or two. Most of your time goes to checking each one against the limits below, adding your real logo and headline in your design tool, and checking the alt text.

You know this work, so you’re the best person to check it. Open every file it made and read every page. If part of it is outside what you know, hand that part to someone who knows it. These are the spots that most often need a fix:

• Look closely at every image: hands, flags, letters, backgrounds. Anything that looks like a ballot, voting equipment, a voting booth, a real place, or a real person gets thrown out. A map pin is a natural icon for early voting, but it can turn into a map that looks like your county. Throw that out too.
• Image tools misspell words and let colors drift. Add your headline in your design tool, where you can proofread it, and fix colors there.
• Don’t give an image tool photos of real people (staff, voters, poll workers) to ‘improve’ them. Use real photos only as real photos, and only with permission.
• Write or check the alt text after you add your headline, so it includes the words on the graphic.
• Check your office’s policy on AI-generated images before you post the first one. The image you post and the prompt that made it may be public records, so keep them with the post’s other records.
