Alternative text provides a textual alternative to non-text content in web pages. It is especially helpful for people who are blind and rely on a screen reader to have the content of the website read to them.

Tips for What to Put in the Alt Tag Field
- If image is active (image link, image button, image map area), then the text alternative should be the function of the image, what the image does, where the link goes.
- If image is text, then the alt text should (usually) be the same as the text in the image.
- If image conveys information, the alt text should convey the same information
- If image is complex as they are in maps, graphs, and charts, use a technique to convey the complete meaning. Some possibilities are to provide on-screen a full explanation; access to data that generated the chart, or longdesc link.
- If the image is only for decorative purposes, or is redundant to adjacent text, use alt=””
