Jiugong grid is one of the most used forms of multiple images posting in social media, with nine images arranged in three rows and three columns to present a related topic story from one microblog. The purpose of this study is to explore the relationship between the big five personality traits and the sequence position of Jiugong grid images. Two hundred thirty-seven volunteers completed a survey on the big five personality traits, and their 4,671 Jiugong grid microblogs with 42,039 photos were also obtained and analyzed. The results showed that users with varied kinds of personality traits could apply the significant position of Jiugong grid to emphasize certain content among multiple photos for a more attractable "story telling" in microblog. Compared with the image sequence position from the perspective of reading order, user personality traits had more relationship with that from the perspective of attention. This study is one of the first investigating the Jiugong grid image sharing behavior, which could theoretically enrich the social media image research from cognitive view and practically reveal the motivation of multiple images usage in social media, such as interface design and marketing purpose.
