Stock Photos and AI: Why Almost Every Website Contains Unlabelled AI Content
Stock archives are filling up with AI-generated images, agencies supply AI material without disclosure — and operators are often unaware. Why the proportion of AI content on your own website is almost always underestimated.
In discussions about AI transparency, the same statement is almost always heard: We do not use any AI. What is meant is: not knowingly. In reality, most websites already contain AI-generated material — it simply arrived through the back door.
The Four Back Doors
- Stock archives: Major platforms have been accepting AI-generated images for years. Today, when you license a stock image, there is an increasing likelihood it is generated — and the platform’s labelling often disappears upon download.
- Agencies and freelancers: Under time pressure, campaign visuals are created in image generators. What is delivered is a JPG file — with no record of its origin on any delivery note.
- Everyday tools: Design software generates backgrounds, text tools draft paragraphs. The line between edited and generated content blurs in daily workflows.
- Legacy content: The blog post from 2024, the team photo from a relaunch — who, after two years, still knows how it was created?
Why This Is Becoming Relevant Now
As long as no one was looking, the unknown proportion of AI content was merely a cosmetic issue. With the transparency obligations of the EU AI Act and machine-readable provenance requirements, this is changing: images increasingly carry their own creation history. What has been generated can be detected — by auditors, platforms, competitors. The question is no longer whether someone knows the AI proportion of your website. The question is whether you know it first.
A Reality Check Takes One Minute
An automated audit reads the provenance traces of your content — C2PA signatures, metadata, image analysis — and shows you the actual status. For almost every established website, the result is a surprise.
And yes, again: technical indicators, not legal advice. But this inventory is the foundation of everything — you can only label what you know.
