Alt text checklist notes for real page image reviews

Alt text is easiest to write when the image is reviewed in context. This builder is for turning a page image list into a practical checklist that separates informative, functional, decorative, and complex images before anyone starts copying final wording into a CMS.

Start with image purpose

The same image can need different alt text on different pages. A lamp photo on a product page may need finish, shape, and placement details. The same photo in a mood board may need less detail or a visible caption instead.

Use the purpose field to decide the job first. Informative images need useful detail, functional images need the action or destination, decorative images may need empty alt text, and complex images usually need surrounding explanation.

Use informative for product photos, examples, and screenshots that carry content.
Use functional for buttons, icons, linked images, and controls.
Use decorative only when the image does not add information in context.
Use complex for charts, maps, diagrams, dense screenshots, or step visuals.

Input lines that review well

Each line works best as image name, purpose, key details, and avoid note. The avoid note matters because alt text often goes wrong by adding claims that the image does not prove, repeating nearby text, or stuffing search phrases into hidden copy.

The live summary shows purpose counts and skipped rows. If rows were skipped, fix the source input before using the checklist as a handoff.

Hero basil planter | informative | Small balcony planter with basil and mint | avoid perfect setup claim
Cart icon | functional | Add lamp to comparison | avoid vague button label
Leaf divider | decorative | Green separator pattern | no description needed
Growth chart | complex | Three-week plant growth chart | include nearby text summary

How to use the output

Treat the output as a review sheet, not a final accessibility sign-off. Copy the CMS handoff when an editor needs suggested alt rows, decorative empty-alt rows, and publication questions in one block. Complex image notes should usually lead to visible page copy, not a long alt attribute.

Check whether surrounding headings already explain the image.
Keep decorative decisions consistent with the page implementation.
For functional images, make the action clear without depending on the image file name.
For complex images, write a short identifier in alt text and put detail nearby.

Limits and common mistakes

This tool does not inspect the live DOM, image rights, product claims, legal requirements, or assistive technology behavior. It helps organize the writing pass so a reviewer can make better decisions faster.

The common mistake is making every image descriptive because that feels safer. Extra description can be noise when an image is decorative or when the visible page already carries the meaning.

FAQ

What does an alt text checklist include?

It includes the image, purpose, key detail to communicate, suggested alt text, and notes about what not to claim.

Can this replace an accessibility audit?

No. It is a writing helper for low-risk review and does not replace a qualified accessibility audit, product review, or legal compliance process.

Why mark decorative images?

Decorative images often need empty alt text or no extra description, because repeating visual filler can make a page harder to use.

What do skipped lines mean?

Skipped lines are rows that do not include image name, purpose, and key details. Rewrite those rows before treating the checklist as complete.
