각 td마다 align=center 값을 넣어줬는데도...
뭘 놓쳤을까요..

if ( ($i>0) && (($i%$list_mod)==0) )
{
echo "</tr>\n\n";
echo "<tr><td colspan='$list_mod' background='$g4[shop_img_path]/line_h.gif' height=1></td></tr>\n\n";
echo "<tr>\n";
}

echo "
<td width=100% align=center valign=top>
<br>
<table width=98% cellpadding=2 cellspacing=0>
<tr><td align=center>".get_it_image($row[it_id]."_s", $img_width , $img_height, $row[it_id], "border:1px solid #f00;")."</td></tr>
<tr><td align=center>".it_name_icon($row)."</td></tr>";

//if ($row[it_cust_amount] && !$row[it_gallery])
// echo "<tr><td align=center><strike>".display_amount($row[it_cust_amount])."</strike></td></tr>";

echo "<tr><td align=center>";

if (!$row[it_gallery])
echo "<span class=amount>".display_amount(get_amount($row), $row[it_tel_inq])."</span>";

echo "</td></tr></table></td>";
