Each image must have an Alternative Text (Alt text)
Descriptive Alt Text for Meaningful Images
The following images must have a descriptive Alt text:
Image is part of the content
Select the image and enter a
descriptive Alt text to the Alt text field on the ribbon.
A linked image is
functional and must have a descriptive Alt text.
Ad Rotator Web Part Images
Add a description in the picture editor. It will be used as Alt text for the picture.
Please note: Wording for Alt text to avoid:
- "image of.."
- "image 1", "image 2"…
- File name
Empty Alt Text for Decorative Images
Empty Alt text (Alt="") should be used for decorative images. An image with an empty Alt attribute (Alt="") is ignored by screen readers.
Note: When you insert an image in SharePoint 2013, an empty Alt text is inserted by default. Leave it alone if it is a decorative image. Add a descriptive Alt text if the image is meaningful or functional.

Text Equivalent for Image of Text
Image of text must have a text equivalent so that screen readers can read its content.
Text equivalent could be:
Select the image and enter its Alt text ("Registration is easy with our new mobile app")
link to the text version of the image (PDF or text document)
If the text content of the image is too long, or has a complex layout (e.g. columns, tables, etc.), an Alt text is not sufficient to describe it. Publishers should link the image to its text version, which could be a PDF or text document.
