Here are a few tips for writing alt-text from the American Federation for the Blind
- There's no need to start with "picture of..." or "image of..." You can jump right in to describing your image.
- Describe the function of the image. Especially if the image is a link, "Search the Card Catalog" is much more useful than "Photo of a collection of books and other reading materials scattered on a library table."
- Brief is better. Remember, syllables are time.
- Put the most essential information first. If it is necessary to use several words, use "Acme Logo: Sun rising over white sand dunes" rather than "Sun rising over white sand dunes: Acme Logo."
- Meaningless graphics need not have meaningful text. If a graphic is being used as a spacer, to push other graphics into position, don't label the thing "Green spacer." Instead, put a space between the quotes of the alt-text so users don't have their train of thought disrupted by such irrelevant information. Use this "non-text" judiciously, though. If you can't think of something to say about an image, that doesn't mean it's meaningless.
- Maintain the alt-text. If your image map is rearranged so that the last item is now "Contact Us," don't forget to move the alt-text, too. Otherwise, that image will still be labeled as "Site Map" and users will be lost.
- Alt-text reflects your professionalism just as much as your choice of images. Spell words correctly.
