You can put HTML and PHP and the Google code right into Style & edit HEADER AREA -> Configure Header Area, and mix & match with the existing Atahualpa tags like %pages

%pages
<table>
<tr>
<td>%logo</td>
<td>Google code</td>
</tr>
</table>
%image

To change the vertical alignment inside the table cells (default:middle) replace <td> with i.e. <td style="vertical-align:top">
