This presentation considers if, and to what extent, visual social media can change the viewer’s perceived image of a tourism destination as well as which types of visual content are most effective in projecting a destination image. The results from an online survey, which compared three different test groups and their image of Mexico City, showed that UGC images from Instagram, as well as random Google images, were more effective at improving destination image than the UGC images reposted by a DMO. Additionally, the study used image annotations to determine which features in images were most important in terms of their contribution to an improvement in overall destination image, presenting a re-usable set of visual features for future work on using annotations in the measurement of visual destination image.
