A PRACTICAL GUIDE

How to use the Image Alt Text Generator.

Alt text depends on the image's role in the page. Describe meaningful visual information; decorative images may need an empty alternative rather than a detailed caption.

Make the workflow fit your task.

Identify the image's role before describing it. Convey the information needed in that page context, distinguishing a meaningful screenshot or chart from decoration that adds no additional information.

Decisions and troubleshooting.

Should alt text describe every visible detail?

Describe the details necessary to understand the image's purpose. Complex charts may also need a nearby longer explanation.

Why is the suggested alt text repeating the caption?

Decide what information the alternative must convey in context. Remove unnecessary duplication while preserving the image's meaningful content.

Try it with your own source.

Replace the example with your material in the task prompt. Keep the requirements you need, then copy the task into WebAct.
