Create Accessible Live Text Rather Than Images of Text
Whenever possible we should author text content in the Drupal editor rather than placing an image of text. Whereas we can describe the image of text with alternative text, we are diminishing the experience for both non-sighted and low-sighted users by doing so.

Incorrect usage of image of text
Correct usage live text and not image of text
Best Practice
Set text as live text whenever possible. If an image of text is required, provide a plain text alternative either in HTML or as a downloadable equally effective alternative format.
Test
Use this image bookmarklet or automated testing tool like WAVE to discover images on a page
- Are there images of text?
- If yes, can you set as live text or provide alternative format?
Exceptions
Things like logos, charts, and graphs can have text set as part of the image as long as alternative text is authored to provide equivalent access.
