Do all wordpress themes support RSS and have a large RSS image placed on it?

1. Rss and the theme are to separate things. If you add /feed to the end of any wordpress install you will see the rss feed. Most browsers will clean the RSS up a bit and style the page- this doesnt have anything to do with the theme You can also add /feed to the end of any catregory URL and you will see RSS for posts in that category
