you could always use a "table"
Code:
<vb:if condition="$post['field8']">
<table>
<tr>
<td>
<img src="images/icons/prestige/cod4/{vb:raw post.field8}.png"> <img src="images/icons/prestige/waw/{vb:raw post.field9}.png"> <img src="images/icons/prestige/mw2/{vb:raw post.field10}.gif"> <img src="images/icons/prestige/bo/{vb:raw post.field11}.png"> <img src="images/icons/prestige/mw3/{vb:raw post.field12}.png">
</td>
</tr>
</table>
</vb:if>
