本研究透過網路問卷平台向Instagram使用者發放問卷，最後蒐集到320筆有效樣本，並從問卷回答者獲得了245名追蹤人數大於一萬人的網紅（個人）名單。經由研究分析發現，在五個圖片品質特徵中，資訊性及原創性的圖片是最有影響力的；圖片對於意見領袖的有顯著的提升效果，且意見領袖性對行為意圖的影響也較準社會關係的影響大。

With the rise of self-media, individuals with unique personalities have become so-called Micro-celebrities or Micro-Influencers. Studies have confirmed that visual effects have become a key factor influencing consumer participation.
Instagram is a social media platform that is popular among young people, and it mainly focuses on pictures and video communication. Therefore, many Internet celebrities have chosen Instagram to run their personal accounts.
How does the visual stimulation of images affect consumer engagement? To answer this research question, this study aims to investigate whether the quality and characteristics of the images presented by Micro-Influencers can enhance the para-social relationship between the fans and their opinion leadership, as well as the influence of behavioral intentions on fans.
A total of 320 valid questionnaires were distributed through an online questionnaire platform, and a list of 245 individual micro-influencers with more than 10,000 followers were collected from the respondents.
This study showed that among the five image quality characteristics, informative and original images were the most influential; the images themselves had a greater influence on opinion leaders, and the influence of opinion leadership on behavioral intention was greater than that of para-social relationships.
