Images
It is important that you provide alternative text for all images included in your guide content.
Alternative text serves several functions:
-
Assistive technologies such as screen readers use it to make the content and function of your images accessible to those with visual or certain cognitive disabilities.
-
It is displayed in place of images, should image files fail to load in a web browser or when a user has chosen to not view images.
-
It provides the ability for search engines and assistive technologies to access image content separate from the page content.
Create alternate text in your LibGuide by going to the text editor and filling out the Alternative Text field on the Image Properties screen.
- Provide alternative text for images, describing their content and function within the text
- Do not repeat information in alt text that is already in the text itself

Media
The Accessibility for Ontarians with Disabilities Act (AODA) stipulates that all video and audio content shared on a public facing website must be captioned and/or transcribed. All embedded podcasts and videos on a Libguide should therefore have a text based alternative (transcript, captions or both).
- For videos shorter than three minutes, follow these instructions for creating your own captions
- For videos longer than three minutes, see closed caption media at the library
Documents
If you are linking to another document you've created within your LibGuide, ensure that document is accessible as well.
All PDFs should be readable and OCRed. TMU has licensed Sensus Access to make documents readable (requires a TMU login).
