Create a plugin that uses the 'parse_templates' hook.

Place this code in the plugin..

$template_hook['headinclude_javascript'] .= ' <script type="text/javascript" src="http://www.terrarienbilder.com/parallax/jquery-1.2.6.min.js"></script>
  <script type="text/javascript" src="http://www.terrarienbilder.com/parallax/jquery.jparallax.js"></script>
  <link rel="stylesheet" type="text/css" media="screen" href="http://www.terrarienbilder.com/parallax/style.css">
<script type="text/javascript">
jQuery(document).ready(function(){';
$template_hook['headinclude_javascript'] .= "jQuery('#parallax').jparallax({});
});
  </script>";

And remove any of the script information you might have pasted into the header template. Just leave this there...

<hr size="1">
<table style="text-align: left; width: 100%;" border="0" cellpadding="0" cellspacing="0">

  <tbody>

    <tr>

      <td style="width: 24%;"></td>

      <td style="width: 802px; text-align: center; vertical-align: middle;">
      <div style="border: 1px solid ; position: relative; width: 800px; height: 150px;" id="parallax">

      <div style="width: 800px; height: 150px;"><img alt="" src="http://www.terrarienbilder.com/parallax/bg_1.png"></div>

      <div style="width: 990px; height: 180px;">
      <img style="position: absolute; top: -40px; left: 650px;" alt="" src="http://www.terrarienbilder.com/parallax/palm_1.png"></div>

      </div>

      </td>

      <td style="width: 24%;"></td>

    </tr>
