Hmm, strange.  It was definitely a .png the first time I looked.  I just
tried again, and then I got the flash.  Now I just get the .png again.

(looks at source).

Ah yes, your code is subtly broken.  You've got a race condition.
You do this in the main document:


But this can be (and in my case probably was) executed before your
js/cookie.js has finished loading, executing and defining the input

You should look at using something like jQuery for things like this.

   <!-- define an empty header -->
   <div id="header"></div>

   <!-- load jQuery library -->
   <script type="text/javascript" src="jquery.js"></script>

   <!-- define a function to replace the header content when the
        document has finished loading -->
   <script type="text/javascript">
     $(document).ready( function() {
