Using AI-generated images on a blog or social media is legal in most places, but whether you can legally use a specific image depends on two things: the licence terms of the tool that generated it, and how you intend to use it — a personal blog post is treated very differently from a paid ad or a product page.
The honest answer is that there is no single yes-or-no rule, and anyone who tells you otherwise is skipping the part that matters. You have to check the commercial-use terms of each vendor you use, because those terms — not copyright law alone — decide what you're allowed to do with the output.
Here's the mechanism behind that. When you type a prompt into an image tool, you are not automatically the author in the legal sense. Copyright protects human creative work, and an image generated from a text prompt may not contain enough human authorship to qualify.
That means the risk usually isn't "someone will sue me for copying their picture." The bigger risk is the reverse: you may not be able to stop other people from using an image you generated, because you may not own it. On top of that, each vendor writes its own licence.
Some grant broad commercial rights to paid subscribers. Some restrict free-tier output to non-commercial use. Some require you to be a paying customer before you can sell merchandise featuring the output. The tool's terms, not your gut feeling, are the deciding document.
A concrete example makes this clearer. Say you run a small coffee-roasting business and you want a hero image for your blog post about single-origin beans. You generate a picture of a burlap sack and a steaming cup.
If you're on a free tier whose terms limit output to personal, non-commercial use, publishing that image on a page that promotes your roastery is a licence breach — even though the image is technically yours to look at. If you're on a paid tier that grants commercial rights, the same image is fine for the blog.
Now say you want to print the same image on 500 bags of coffee you'll sell. That's a different use again, and many vendors treat merchandise differently from web publishing. Same image, same tool, three different answers.
This is why the question "is it legal?" can't be answered without naming the tool and the use.
According to our AI tool database, Midjourney's plans run from Basic at $10/mo through Standard at $30/mo and Pro at $60/mo, and Adobe Photoshop is available as a standalone subscription at $20.99/mo or as part of the Photography Plan at $9.99/mo. Both are listed as image tools in that database, but here's the crucial limitation: the database records pricing and capabilities, not licensing terms.
It does not tell you what each vendor's commercial-use policy says, and I won't pretend it does. That information lives on each vendor's own terms-of-service page, and it changes — sometimes quietly, sometimes with a date stamp. Treat the vendor page as the only reliable source, and re-check it if you're doing anything commercial.
Where this advice fails: it doesn't cover trademark or likeness issues. If your generated image resembles a real person, a logo, or a protected character, licence terms won't save you — that's a separate problem. It also doesn't cover jurisdictions where AI output rules are still being written.
And it doesn't cover images you generate with one tool and then edit in another, because the second tool's terms may add their own conditions. Practical tip: before you publish anything commercial, save a screenshot of the vendor's terms page with the date visible. If a dispute ever comes up, that dated record is worth more than your memory of what the page said six months ago.
If your reference material contains no licensing information — as ours doesn't — say so plainly rather than filling the gap with confident guesses. The safest habit is simple: check the terms, match them to your use, and when in doubt, ask the vendor directly.
