Adds <media> tags to your feeds with post thumbnail support which came with WP 2.9 version. This plugin is based on Andy’s (http://andy.wordpress.com/) MediaRSS plugin. If you use that MediaRSS plugin unactivate it before activating this plugin.
MediaRSS is a way of embedding media into your feeds. The specification at http://search.yahoo.com/mrss/ provides for many kinds of media: audio, video, etc. This plugin is equipped to locate img tags in your posts and generate XML code that can be used by feed readers.
Also included are code samples demonstrating how to extend the plugin’s functionality to meet your needs. Some PHP experience is assumed.
