The study collected and analyzed data on the process by which web users conduct real image search tasks. With the additional methods of non-obtrusive observation, questionnaire, and interview, this study investigated the image search behavior and relevance judgment of 34 college students from different subject domains. Pre- and post-search analysis was also conducted. The results include: users mostly search for specific images like people to fulfill their recreational needs; topicality, accuracy, and sense of aesthetics are the top three relevance judgment criteria; associativeness and technical details increase in importance, whereas accessibility decreases in importance from pre-search to post-search; user background, image needs, and data request types also have an influence on relevance judgment. To conclude, some suggestions on image literacy and image retrieval system design were provided.
