Alternative Text (Alt Text) for Images

Modified on Mon, 20 Jun 2016 at 03:47 PM

Alternative text serves several functions:

  • It is read by screen readers in place of images allowing the content and function of the image to be accessible to those with visual or certain cognitive disabilities.
  • It is displayed in place of the image in browsers if the image file is not loaded or when the user has chosen not to view images.
  • It provides a semantic meaning and description to images which can be read by search engines or be used to later determine the content of the image from page context alone.


To ensure ALT text is added when you are inserting images into your page:


Insert a short, brief description about your photo in the "Image Description" field.  You may also add a short title to the "Title" field.


Insert or Edit an Image


Or when you are inserting a thumbnail or banner image to your page, you may see something like this:


Insert ALT text on banner or thumbnail images
