Improved techniques that facilitate the use of podcasts are disclosed. The improved techniques can pertain to publishing, hosting, accessing, subscribing, managing, organizing, searching, browsing, transferring, and/or playing podcasts. According to one aspect, tags are embedded into syndication feeds (e.g., RSS feeds) that may be made available for distribution by an online media store to facilitate the management of podcasts. Such tags can include a block tag that may be embedded into a syndication feed to indicate whether the feed is to be blocked from being included in the online media store. According to another aspect, management of podcasts may be facilitated by other mechanisms. In accordance with one embodiment, a user may challenge the ownership of a podcast to block or remove a podcast from the online media store. In accordance with another embodiment, images may be stored to allow efficient retrieval of the corresponding episode(s) of a podcast.
