  In this paper, we demonstrate the possibility of predicting people's
hometowns by using their geotagged photos posted on Flickr website. We employ
Kruskal's algorithm to cluster photos taken by a user and predict the user's
hometown. Our results prove that using social profiles of photographers allows
researchers to predict the locations of their taken photos with higher
accuracies. This in return can improve the previous methods which were purely
based on visual features of photos \cite{Hays:im2gps}.
