Assigning an image to dated archives

On my website I have a bunch of articles published on different dates, just like a standard blog.

In the sidebar I am using the standard “archives” widget to list all of the months, users can then click on the month and see posts only from that month.

What I would like to achieve is to be able to display all of the links to the months on a single page rather than in the sidebar, but more importantly with an image associated to them.

I am not talking about creating a custom archive and assigning an image to that, I want to assign an image to the default date/month that WordPress already generates and sorts by.

Does anyone know of a solution to this? Perhaps you could point me towards some resources to implement.

Many Thanks,
Brett.
