The emergence of Web 2.0 technologies has greatly enhanced capabilities of online social networking. Flickr is a social networking platform that enables users to share digital pictures. In contrast to other social networking sites, photos are the basic unit of information exchange in Flickr. We analyse relationships between users with a data set that covers 35\% of the whole Flickr community. We define metrics of success for content, content providers, the relationship between both and identify implications of having information about successful content. We establish performance criteria and examine the correlation between the performance and the connectivity of users. Based on these key metrics we identify high quality content producers for a given category.
