- Skip “image of” or “picture of.” Screen readers already say it's an image.
- For charts, give the main takeaway, not every number.
- Don't use pictures of text. Type the text instead, so everyone can read and search it.
Microsoft can suggest alt text automatically. Always read it and fix it, because suggestions are often vague or wrong.
Quick check
- ☐ Every meaningful image has alt text.
- ☐ Decorative images are marked decorative.
- ☐ No important information is only in an image.
