Why AI can't see the photos on your website

Your website is probably full of photos. The cake you decorated, the garden you transformed, the room you fitted out. To a customer, those images say everything. To an AI assistant, they say almost nothing.

AI tools like ChatGPT, Gemini and Perplexity read text. They don't look at your pictures the way a person does. So when your best work lives only in a photo, with no words to explain it, that work is invisible to the tools more and more of your customers now ask before they buy.

This post explains why your images go unseen by AI, what you're losing because of it, and the simple habit that puts the information back where AI can find it.

Why AI reads words, not pictures

AI assistants build their answers from text they can read across the web. They can describe an image if you upload one directly, but that's not what happens when a customer asks about a local business. The AI pulls from written descriptions, captions and page text. If the meaning of your page lives inside the image file, it falls straight through the gap.

A photo is a closed box

A ceramicist in Stoke might have a gallery of hand-thrown bowls, mugs and serving plates. Lovely to a visitor. But to an AI tool, that gallery is a row of files named something like IMG_4471.jpg. No prices, no materials, no "made to order", no "ships across the UK". The information a customer needs is locked inside pictures the AI can't open.

What AI uses instead

AI fills the gap with whatever text it can find — your headings, your written descriptions, your reviews and your directory listings. If those are thin, the AI's answer about you is thin too. AI My Site scans the major AI platforms and shows you exactly what they can and can't tell a customer about your business right now.

What this costs you in real searches

When someone asks an AI assistant "where can I get a custom-framed print near me" or "who does same-day dog grooming", the AI is matching that question to text. Pictures don't enter into it. The business that wins the recommendation is usually the one whose page says, in plain words, exactly what the customer asked for.

Service businesses

A dog groomer in Norwich whose homepage is a slideshow of happy dogs, with no written list of services, breeds catered for or opening times, gives the AI nothing to match against. A competitor with the same kind of photos plus a plain-text list of what they do gets recommended instead. The photos may even be less impressive, but the words tip the balance.

Makers and retailers

A picture framer in Bath might show dozens of finished frames but never write the words "box frames", "canvas stretching" or "conservation glass". Those are the exact words customers use when they search. If the words aren't on the page, the framer doesn't appear in the answer.

How to put the information back in words

Here's the reassuring part: you don't need to remove a single photo. You just need to add the words that explain them.

Describe what's in the picture

For every important image, add a written caption or a line of text nearby that says what it is. Under a photo of a finished kitchen, write "Shaker kitchen in matt sage, fitted in a Victorian terrace". That one sentence gives the AI something real to work with.

Fill in the alt text

Most website builders have a box called alt text — a short written description attached to each image, originally meant for people using screen readers. It takes seconds to fill in, and AI tools can read it. Describe the image plainly: "physiotherapist treating a patient's shoulder in a Plymouth clinic". Avoid leaving it blank or letting your builder fill it with a filename.

Write the page around the work

Don't let a gallery stand on its own. Add a few short paragraphs of plain text that name your services, your materials, your prices and the area you cover. The photos make the page appealing. The words make it findable.

Common mistakes to avoid

• Relying on a photo-only homepage. A beautiful image carousel with no readable text gives AI nothing to quote.

• Leaving alt text blank. Most builders auto-fill it with a filename like "DSC_0098", which tells AI tools nothing useful.

• Putting prices and details inside the image itself. Text baked into a graphic or poster can't be read as words.

• Using vague captions. "Our latest project" is no better than no caption. Name the what, the where and the who.

• Assuming AI sees what your customers see. People read pictures instantly. AI tools still mostly read text.

How long until it makes a difference

Adding captions and alt text is something you can do in an afternoon, but the change won't show up in AI answers the same day. Perplexity tends to pick up fresh website text quickly because it follows links as it answers. ChatGPT and Gemini work on slower cycles, so expect four to eight weeks before new descriptions filter through, and up to twelve weeks for the change to settle everywhere.

The pattern that works is consistency. Describe the same work the same way on your website, your Google listing and your directories, so the version you want is the easiest one for AI to find. Checking your AI readiness score first shows you which pages are currently letting your images do all the talking.

You've learned why AI tools overlook the photos that mean the most to your customers, and how a few lines of plain text can make that work visible again. The fix costs nothing but a little time, and it puts you ahead of every competitor still hiding their best work inside a picture.
