Channel preview picture missing in rss feed?

Where has the channel preview picture in the rss feed gone to? Adding to the channel description, it helped decide if the new channel was of interest and would possibly be added to my subscriptions. We need all the help available to keep track of the sheer amount of new channels every day. Or is there another newsfeed featuring preview pictures available that I am not aware of, other then http://feeds.feedburner.com/miroguide...
