Image Alternatives: Describe the Purpose in the Page Context

Use a small fictional page

Choose an owned or clearly licensed sample image and place it in a local practice page. Try it as an informative illustration beside a learning task, as a purely decorative background-like accent and as the only content inside a link. Keep the page offline and avoid real learner photographs or claims.

This supports content and interface thinking alongside UI/UX learning in Jaipur. The exercise is a focused image-purpose review, not a complete accessibility audit.

Identify the information that matters

For an informative image, write a concise alternative conveying its relevant meaning in that page. A filename or a list of SEO keywords does not explain why the illustration was included. Avoid repeating nearby prose when that repetition adds no useful information.

If an image contains essential complex information, a short alternative may need a nearby detailed explanation or another accessible representation. Do not try to squeeze an entire chart or instruction sheet into a vague phrase.

Recognise a genuinely decorative use

When an img element is purely decorative and adds no information or function, an empty alternative, alt="", can avoid unnecessary announcements. Omitting the attribute is a different choice and can leave assistive technology with an unhelpful filename. Judge decoration by page purpose, not by whether the artwork looks attractive.

Describe a function when the image is a control

If an image is the only content of a link or button, the alternative should communicate the destination or action. Describing the icon's shape alone may leave the control's purpose unclear. Check the surrounding accessible text so the same action is not unnecessarily repeated.

For an image beside sufficient link text, its role may instead be redundant decoration. Review the complete control rather than deciding from the image file in isolation.

Keep an explicit review record

• Where is the image used and why is it there?
• Is it informative, decorative, functional or more complex?
• What information or action must remain understandable without seeing it?
• Does the proposed alternative duplicate or omit essential nearby context?

Test the explanation against the task

Read the page content and proposed alternatives as a sequence, then ask whether the task still makes sense. Use an appropriate accessibility review for a real release; a text-only read-through is only one check.
