You sure you did not mix your install files from a reviewpost install or so?
I am looking in searchbox.tmpl from the photopost distro and the contents are this
<?php
echo<<<PPPRINT
<table cellpadding="0" cellspacing="0" border="0">
<tr>
<td align="right">
<input type="text" name="si" style="font-size: 8pt;" size="15" value="$si" />
<input type="image" align="bottom" src="{$Globals['idir']}/go.gif" />
</td>
</tr>
<tr>
<td colspan="6" align="right">
<span class="{$Style['small']}">{$Globals['pp_lang']['recent']}: <a href="{$Globals['maindir']}/showgallery.php?cat=last1&forcat=$cat">{$Globals['pp_lang']['lastday']}</a>
<a href="{$Globals['maindir']}/showgallery.php?cat=last7&forcat=$cat">{$Globals['pp_lang']['last7']}</a>
<a href="{$Globals['maindir']}/showgallery.php?cat=last14&forcat=$cat">{$Globals['pp_lang']['last14']}</a>
<a href="{$Globals['maindir']}/showgallery.php?cat=all&forcat=$cat">{$Globals['pp_lang']['allimages']}</a>
</span>
</td>
</tr>
</table>
PPPRINT;
?>
