hmm now I am as baffled as ever....
I thought I had it all figured out...
I left the php calls for the png script in the header and footer php files, and then merged all of the remaining content into the template.html file. the script really has the only PHP dependency I had.
There are no more html tags in the header and footer files...
<?php ob_start(); ?>
<?php
include_once 'replacePngTags.php';
echo replacePngTags(ob_get_clean());
?>
that's it! nothing else...
the file it calls is this:

* Modifies IMG and INPUT tags for MSIE5+ browsers to ensure that PNG-24
* transparencies are displayed correctly. Replaces original SRC attribute
* with a binary transparent PNG file (spacer.png) that is located in the same
* directory as the orignal image, and adds the STYLE attribute needed to for
* the browser. (Matching is case-insensitive. However, the width attribute
* should come before height.
*
* Also replaces code for PNG images specified as backgrounds via:
* background-image: url(image.png); or background-image: url('image.png');
* When using PNG images in the background, there is no need to use a spacer.png
* image. (Only supports inline CSS at this point.)
*
* @param string $x String containing the content to search and replace in.
* @param string $img_path The path to the directory with the spacer image relative to
* the DOCUMENT_ROOT. If none os supplied, the spacer.png image
* should be in the same directory as PNG-24 image.
* @param string $sizeMeth String containing the sizingMethod to be used in the
* Microsoft.AlphaImageLoader call. Possible values are:
* crop - Clips the image to fit the dimensions of the object.
* image - Enlarges or reduces the border of the object to fit
* the dimensions of the image.
* scale - Default. Stretches or shrinks the image to fill the borders
* of the object.
* @param bool $inScript Boolean flag indicating whether or not to replace IMG tags that
* appear within SCRIPT tags in the passed content. If used, may cause
* javascript parse errors when the IMG tags is defined in a javascript
* string. (Which is why the options was added.)
* @return string

All it does is search for png tags and replaces them with a transparent placeholder into tricking IE not to show that corny gray border. It doesn't do anything with the <head> or <body> tags...
I merged my CSS files as well.
It all looks ok - lol - but I still have that damned "powered by" at the top...
