The Google Forms API is currently in Open Beta. For Google Apps Script users the new Forms API is worth keeping an eye on as it enables functionality not currently included in the native FormsApp
service. In this post from Kanshi Tanaike an example is looked at where the Forms API is used to insert an image to a question. If you are interested in trying this example out remember that you currently need to apply for access at the Early Adopter Program page.
