Inserting images into Matching Drag N Drop

Hi, I'd like to insert images into a Matching Drag N Drop question. I'd like for users to match four or five icons to a description of the icons' function. I have not used Quizmaker very long, but it looks like I can only use text in the Matching Drag and Drop fields. Is there a trick to inserting images or is there another way to do what I'm looking to do?

Thanks!
