Fluid, Rotating Headers - yet another thread

Having given up on Themeframe for the foreseeable future, I downloaded the latest version of Atahualpa. Within a day of retracing steps I was reminded of that enduring frustration: Not having a fluid header that would rotate images.

The most amazing new developments seem to be in the simple solutions discussed in the thread:

[SOLVED] Header Image & Fluid Width Question

In which Tammy showed us how to add the following to the "configure header area":

<img src="http://yourdomain.com/wp-content/themes/atahualpa349/images/header/yourimage.gif" width="100%">

Any chance that this bit of info, one line for each image, could be incorporated into the rotate function? If so, where?

Coming at it from another direction, it seemed like lmilesw had it solved when he wrote:

div.header-image-container img {
width:100%;
height:100%;
}

"If you leave the height blank the image will re-size and retain the aspect ratio instead of squeezing and stretching the image."

This works perfectly other than the full height static image that is displayed behind the rotating images (which you can see on my test site, assuming you don't have your monitor set to a width of 2048 or more):

(If I remove %image from the Configure Header Area there is no image at all, but if there could be some way to avoid having it retrieve "The rotating (or static) header image," but just one or the other... OK, I'm rambling.)

Any further ideas on this illusive item?
