Alternate text on images and graphics can be read by devices that help those with disabilities access and understand the content of the page. Alternate text is a simple caption or summary of the image being displayed. If, for example, you use a photo of your newsletter to link to your newsletter, you would want to include some alternate text to explain what the photo is to your non-sighted visitors or those needing other assistance. This caption can be something as simple as "graphic link to our newsletter". When the assisted device reaches the graphic in the content it will alert the visitor audibly and read the alternate text.
