15. A computer-implemented system, comprising: an input device enabled to generate an idea-image association that associates an image with an idea based on data that indicates user interaction with the image in a presentation of search results that correspond to a first search query, wherein the idea is determined to be related to the first search query; a database enabled to store the idea-image association and other idea-image associations; and a processor enabled to provide the image for display in a presentation of search results that correspond to a different, second search query, wherein the processor is enabled to select the image for display in the presentation of search results that correspond to the second search query based on (i) determining that the second search query relates to the idea and (ii) identifying from the stored idea-image association that a match exists between the idea that the second search query relates to and the idea to which the image is associated.
