Rotating header images, link to posts.

Hi there,

I've tried doing some searching through the forum for this question, but cannot seem to find an answer. I would like to somehow assign an individual blog post to a rotating header image, instead of having it link back to the home page. I've found the threads that describe how to change the link to something else, but I would like to be able to have the link change each time the header image changes. Is this possible?
