I want to use radio buttons with a picture (rather than a text caption) as a stimulus. I have figured out how to do this by putting a picture on each page of the survey. However, when I include "/required = true" as an option with the radio button, the stimulus disappears if there is a non-response. This makes it essentially unproductive to require a response as the participant needs to be able to see the picture to respond.
Any other ideas about how to use a picture as the radio button prompt AND have the picture remain on the screen if a response is required?
