HA! I found that little sucker.

It's in the skin1\altskin.css file

#header .line1 .logo {
  background: url(images/custom/top_image.jpg) no-repeat right top;
  height: 192px;
  position: relative;
  padding-top: 0px;
  margin-left: 0px;
  width: auto;
}

I put my bannerdogs.gif in the skin1/images/custom/ folder change the top_image.jpg to bannerdogs.gif and tada!!!

I would also think that if you had a Flash File you could modify the head.tpl file and insert it in here somewhere.
