    1. No, see decorative images [stop]
    2. Yes, continue
  2. Can a concise and plain-text description provide an equivalent to the image?

    1. No, see complex images [stop]
    2. Yes, continue
  3. Is the image part of a control?

    1. Yes, see control images [stop]
    2. No, continue
  4. Are there multiple images which are all views of one object?

    1. Yes, see multiple images [stop]
    2. No, continue
  5. Does the image use another method of providing an alternative?

    1. Yes, see equivalent alternative text pass [stop]
