I teach Field Biology, where students learn to identify different species of plants and animals.  There are many times when I would like to add images as answer choices in multiple choice or matching questions.  For instance, having students match pictures of animal tracks with the names of the animals who made them.  Or, give them a question about plant adaptations and then have multiple pictures for them to choose from in order to answer the question.

Actually, this would be cool in categorization questions and sorting questions too!  It would be helpful to be able to insert images that students have to sort or drag and drop into set categories.
