The short version: copying a viral ChatGPT photo editing prompt is fine, but copying it blindly is where people get burned, either legally (uploading someone's face without consent) or practically (the prompt doesn't do what the screenshot promised because your photo, your model version and your settings are all different). Strip the prompt down to its structure, swap in your own descriptive detail, and always check whose face and whose style you're feeding into the tool before you hit enter.
Why the exact prompt you copied won't give you the exact result you saw
I want to get this out of the way early because it's the bit nobody selling prompt packs wants you to know: the prompt is maybe 40% of the result. The other 60% is the input photo, the resolution, the lighting, the model version running that week, and sometimes plain luck. I've taken a prompt word for word from a LinkedIn post with 4,000 likes, run it against a headshot, and got something flat and slightly odd looking, while the original poster's version looked polished and warm. Same words. Completely different outcome.
That's not a fault in the prompt. It's a fault in how people talk about prompts, as if they're a recipe with a guaranteed output. They're closer to a brief you'd give a junior designer: the more specific and well structured the brief, the more consistent the result, but two different photos going through the same brief will still come out differently. If you want to understand how to build that specificity yourself rather than relying on someone else's leftovers, my guide on descriptive words for crafting impactful business prompts is a good place to build that muscle.
The safety checklist before you copy anything
Before you paste someone else's prompt into ChatGPT and attach a photo, run through this in your head. It takes about thirty seconds once it's a habit.
- Whose face is in the photo? If it's not yours and not covered by an existing agreement, you need consent, full stop, even if it feels like "just a bit of fun with an AI filter."
- Does the prompt name a living artist or a specific studio style ("in the style of Studio Ghibli," "like a Pixar character")? That's a copyright grey area that OpenAI's own usage policies have tightened around, and using it for anything commercial (a client campaign, an ad, a paid product) is riskier than using it for a personal profile picture.
- Is there a child in the photo? Most platforms, ChatGPT included, restrict certain transformations involving anyone under 18, and enforcement has got stricter through 2026, not looser.
- Are you uploading a client's or colleague's photo from a work folder? If so, you're processing someone's personal data on a US-based server. In the UK and EU that's a GDPR question, not a style question, and I'll come back to that.
- Does the prompt include a brand logo, packaging, or trademarked product? Fine for internal mockups, riskier if it's going into published marketing without a proper licence check.
If you tick "yes" to consent, no named artist, no minors, and no live client data, you're in reasonably safe territory to adapt and go.
The client photo I almost got wrong
Last year I was helping a small hospitality client build out a "team faces" campaign for their socials, turning staff headshots into a warm, illustrated house style using ChatGPT's image tools. I'd found a prompt structure doing the rounds that turned photos into a soft, Pixar-adjacent cartoon look, and it had lovely results in the examples people were sharing. I adapted it, tested it on my own photo first (always test on yourself before anyone else), loved it, and was ready to run it across the client's staff folder of twelve photos.
Then I looked at the folder. One of the twelve was a work experience student, seventeen years old, who'd been photographed for an internal newsletter months earlier and whose photo had ended up in the shared marketing drive by accident. Nobody flagged it. If I hadn't checked, that photo would have gone through an AI transformation and potentially out onto a public Instagram grid, for a minor, with no parental consent on file for that specific use.
I pulled it before running the batch, went back to the client, and we got a proper written consent from the parent for a different, more neutral use instead. It cost me an afternoon and a slightly awkward email. It would have cost the client a lot more if it had gone out and someone had complained, or if a platform had flagged the account. That's the bit that never makes it into the "look what I made with ChatGPT" posts: the checking is the actual work, the prompt is the easy part.
What "adapting" means, step by step
Copying a prompt word for word and swapping nothing is how you get generic results that look like everyone else's. Here's the process I use when I find a good prompt someone else has shared:
- Step 1: Read it for structure, not words. Most good photo editing prompts follow a pattern: subject description, style or medium, lighting, mood, composition, and a technical instruction (aspect ratio, background treatment, what to keep unchanged). Identify which part is doing which job.
- Step 2: Strip out anything brand or artist specific. Replace "in the style of [named artist]" with a description of the actual visual qualities you like, e.g. "soft pastel palette, rounded shapes, gentle rim lighting, slightly desaturated" instead of borrowing a name.
- Step 3: Swap in your own subject detail. This is where most people are laziest. If the original prompt says "a woman in a blue blazer against a neutral background," don't just change "blue" to "green." Describe your actual photo: the real backdrop, the real expression, what needs to stay exactly as it is (a company badge, a specific hairstyle, glasses).
- Step 4: Add a preservation instruction. I always add a line like "keep facial features, proportions and skin tone accurate to the original photo" because without it, some transformations drift the face further from reality than you'd want, especially over multiple regenerations.
- Step 5: Test small before you scale. Run it on one photo, check it against the person if they're available, then batch the rest. Don't run twelve staff photos overnight and check them in the morning; check the first one immediately.
- Step 6: Keep a record of the final prompt you used. If a client asks six months later how their headshots were made, or a photo needs regenerating for a different platform size, you want the exact wording saved, not a memory of "something like the one from that LinkedIn post."
If you want a fuller walkthrough of building these from scratch rather than adapting someone else's, I've written a dedicated piece on how to use ChatGPT to create photo editing prompts for your brand that covers the brand-consistency side in more depth than I can fit here.

The legal bit people skip past
I'm not a lawyer and this isn't legal advice, but as someone who's had to sit through data protection training more times than I'd like, here's what I tell clients plainly. If a photo shows an identifiable person, uploading it to any AI tool, ChatGPT included, is processing personal data. Under UK GDPR that means you need a lawful basis to do it. For staff photos used internally with existing employment consent, you're usually fine. For customer photos, competition entries, or anything scraped from social media because "it's public," you're on shakier ground, because public visibility doesn't automatically mean you have the right to run it through a third-party AI system and republish an altered version.
The practical fix is boring but it works: get explicit written consent for AI-based photo transformation specifically, don't rely on old consent forms that only mention "photography for marketing," and tell people what tool you're using. Most people don't mind at all once you ask, in my experience, but the asking has to happen before, not after.
On the copyright side, OpenAI's usage policies (worth reading directly rather than trusting a summary from a random LinkedIn thread) restrict generating images that closely mimic a specific living artist's style for commercial use, and restrict realistic depictions of real public figures in ways that could mislead. A copied prompt that worked for someone's personal fun account might breach those same policies the moment you use it for paid client work.
Where prompts are worth copying from, and where they're not
Free prompts shared openly on Reddit, X, or LinkedIn by someone showing their own before-and-after work are usually fine to adapt, because you can see exactly what input photo produced what output, which tells you how much of the magic is really the prompt. Paid "prompt packs" are more of a mixed bag. Some are well tested and save you hours of trial and error. A lot are repackaged versions of things freely available, sold to people who don't know that yet. I wrote a full breakdown of how to tell the difference in what are AI prompt packs, and are they worth buying, and the short version is: ask to see three before-and-after examples using different subject photos before you pay for anything.
The best source, honestly, is your own testing log. Every time you find a prompt structure that works well for headshots, product shots, or team photos, save it with a note on what kind of source photo it works best with. Over six months you'll build a small personal library that's more reliable than anything you could buy, because it's tested on your actual subjects, not a stranger's.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
A safer weekly workflow if you're doing this for a business
If photo editing with AI is becoming a regular part of your marketing, treat it like any other input-dependent process. The same discipline that makes AI copywriting work, described well in the guide on writing prompts that work for small business owners, applies here: vague input, vague output, every time.
- Keep a single shared document of approved, tested prompts your team can reuse, with a note on what consent is needed for each type of use.
- Before any batch job, check the photo folder for anyone under 18, anyone who's left the company (their consent may no longer cover current use), and anyone who's specifically asked not to be photographed for marketing.
- Run a test image first, every single time, even if the prompt worked perfectly last week. Model updates happen quietly and results shift.
- Store the original, unedited photo alongside the AI version. If a subject ever asks for it to be taken down or wants to see the source, you need both.
None of this is complicated. It's the same care you'd apply to any customer data, just applied to something that feels playful because it involves cartoon filters and Pixar eyes instead of spreadsheets.

Frequently asked questions
Is it illegal to use ChatGPT to edit a photo of someone else?
Not illegal on its own, but if the person is identifiable and you don't have their consent, especially for commercial or public use, you're likely breaching UK GDPR's requirement for a lawful basis to process personal data, separate from any copyright question about the prompt itself.
Can I copy a prompt from someone's viral before-and-after post?
Yes, prompts themselves generally aren't copyrighted, but the exact result you saw depended on their specific photo and settings, so expect to adapt the wording to your own subject rather than assuming it will produce an identical style out of the box.
Are "in the style of" prompts naming a real artist safe to use?
They're riskier than describing the visual qualities yourself, particularly for commercial work, because they can breach both platform usage policies and the artist's own rights, so replace the name with a plain description of colour, texture and composition instead.
Do I need consent to run a colleague's headshot through an AI photo editor?
Yes, and ideally consent that specifically mentions AI-based transformation rather than an old blanket marketing photography agreement, because most existing consent forms were written before this kind of editing existed.
