The generic advice for the alt attribute is that it should replace the
graphic, not describe it. (You can use the title attribute to describe the
graphic, if desired.)
- If the graphic contains text or a logo that includes text, make the alt
the same as the text. (For example, alt="Foo Corporation", not
alt="Corporate logo, 402K".)
- If the graphic is a bullet or some similar glyph, find something in
ASCII that approximates it. (For example, alt="*", not alt="medium-sized
This works better with text browsers (or graphic browsers with images not
loaded) than with speaking browsers, so you may want to use a different
approach if your audience includes a lot of users who have audio access.
- If the graphic is a pure decoration that's there for aesthetic value
rather than meaning, it has no equivalent in text, so you can simply use
alt="" to remove it from the text stream so it won't distract the text user.
- If the graphic is itself part of the content - for instance, a part
drawing - a description might be appropriate, but even better is a
description that replaces the graphic content. For example, alt="Tab A goes
into Slot B", rather than alt="Picture of Tab A and Slot B".
