1. An apparatus comprising: a processor; and a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to: formulate, in response to receiving an input question, an answer to the input question; identify, based on the answer to the input question, a set of candidate images from a corpus of information, the set of candidate images relating to the answer, wherein the corpus of information includes more than one document; determine a respective confidence value for each image in the set of candidate images, wherein each respective confidence value is a numerical value indicating similarity and relevance between the respective candidate image and the answer to the input question; assign a respective proportional value to each candidate image of the set of candidate images, wherein each respective proportional value is a numerical value indicating a size of the respective image with respect to a size of a display area used to display the answer to the input question; select a first subset of the set of candidate images to provide in the display area based on both the respective confidence values and the respective proportional values of the images in the set of candidate images, the first subset comprising one or more images of the set of candidate images; and output the first subset for display in the display area together with the answer to the input question.
