the rss feed generator includes whatever the post includes. The text and the links. It does not include the attachments or automatically generated links to the attachments, unless there is a link within the post text to it.
Beyond what Gizmo already mentioned about updating your rss feed reader client settings, you could just update your rss feed to include 0 chars of the post content. ie; titles only. but thats a jerk-move. and goes against the spirit of how rss feeds are designed to work.
