What the most efficient way to insert an image based on the day's date?

For example, on Monday April 18, 2005 it would generate:
[img src="http://www.domain.com/images/20050418.jpg"]

It would also be handy if it could check to see that the image exists before inserting it, and if not continuing to subract a day from the date until it found an image.

Anyone have any idea how I could do this?
