Make images accessible

By following the basic principles outlined here, we can make our LibGuides more accessible to individuals with disabilities.

• Adding alternative text to images is one of the easiest accessibility practices to implement. 
• Alternative text may be provided in the HTML alt attribute or in the surrounding context of the image.
• Every image must have an alt attribute.
• Decorative images still need an alt attribute.
• Alternative text should:
  • present the CONTENT and FUNCTION of the image.
  • be succinct.
• Alt text of a functional image (e.g., an image within a link) should describe the function as well as the content.
• Alternative text should not:
  • be redundant (be the same as adjacent or body text).
  • use the phrases "image of…" or "graphic of…".
• Appropriate alternative text depends heavily on the image's context. Use this Alt Text Decision Tree to guide your choices.
