Moving Pictures...

I would like to have the IMWI countdown clock display in my training log, not in a daily post, but at the top under the goals.

This is what I want to display:  http://www.ironmanwisconsin.com/wisclock.html

But I have no idea how to do it.  I've seen other logs with similar changing images in them, but I just can't figure it out!

Please help!

TIA
