Add some way to control the primary image of posts.

Should this be stored in the database so it can be changed by admins? Should this just be a URL in the XML file? Pin this down further before working on it.

I think a different attribute for storing the image pointing to a URL would be fine. Else, we could store the images at a "secret" location and have the code deserialize them by just calling their name(then some code would do the locate the image magic).

Problem is I don't want to overcomplicate this with secret locations and extra services, I just want this one service to provide all that data. And maybe that means it's worth delaying this until we have a DB so we can just read the image straight out of the DB instead of trying to do weird stuff with xml references.
