Flickr is a photo-sharing network. What can we learn from it? Maybe we can learn photography on it. Is it useful in academia? This article tells us Flickr can serve as a database in which subject-relevant images may be searched for/consulted/viewed/used. The study addresses three main question: What types of images tagged with academic terms are posted to Flickr and how do they differ between subject areas? Are some subject areas more frequently represented in Flickr? Does term-frequency analysis of accompanying tags provide any additional insights into the types of images investigated and the reason for their placement? The study process mainly includes images tagged, image content analysis, and term-frequency analysis of associated tags.
