So obviously my question is not making much sense so I will try to clarify.
So if you take a look at my current feed here: http://myheadpiece.com/pages/myfeed.aspx
You can see the media:content tag. But if you take a look at this feed from flickr: http://www.flickr.com/services/feeds/photos_public.gne?tags=toy&format=rss_200
This feed is in the correct format that my plugin can read. As you can see the media:content tag has additional information within the tag that is different from my feed. Obviously I can accomplish this by writing all of the xml in a static manner, but I want to do this dynamically from my SQL database that I have already created. So my question is this, how can I write my code in my code behind to emulate the media:content tags that are seen in the flickr feed so that my plugin can read my own mRSS feed?
