How can I add image to schema.org/QAPage markups?

Question

I need to display one image alongside with question text. Theoretically it's possible as I can see in https://schema.org/QAPage , but how with Q2A? Where I do need to edit?

Answer 1

I managed to use one image but it turns out that my effort is useless. Google does not support all Schema.org markups, and in all supported markups, it does not display all elements.
