In higher education, there is an increasing expectation that students are able to access course content online, in the form of PowerPoint presentations, Word documents, and even original material added directly to the Course Management System. When adding images to digital content, it is important to understand that students who require screen readers may be limited if alternative text (alt text) is not added. Adding appropriately worded alternative text to an online image greatly improves the accessibility of your course content.
In Microsoft Office products, alt text can be added by clicking on the Format Picture menu. Type a phrase or short sentence into the description window.

In D2L, when an image is added using the Insert Image icon, you will be prompted to add Alternative Text. If the image doesn’t add any additional content, you can click, This image is decorative.

Your alt text should describe the relevant content that the picture conveys to a sighted person. As an example, the alternative text for the screenshot on the left might read, “The Format Picture Menu in Microsoft Word has a window to type in a title and a description.” It is not necessary to use phrases like, “A picture of…” at the start of your text.
WebAIM has a great article on alt text, that can clarify the purpose and process, and help you decide on the best phrasing to use in different situations.
Removing barriers to learning is an important concept to embrace in education.
