Hello,
I'm playing with some RSS functions, and I like to fetch/extract the (image:thumbnail) url from the CNN RRS Feed: http://rss.cnn.com/rss/edition.rss
In this (and other) RSS feeds there can be mediafiles (image:thumbnail) that seems to be impossible to grab and display together with the rest of the feed output. The <image> tag maight be an extenstion unknown to System.ServiceModel.Syndication, but it must be possible to fetch it some way...? And I like to use the <Image> Url for the image tag below.
Please don't suggest "google that" or something, I have already done that for a few days now...
