Look for:

<div>
					$vbphrase[posts]: $post[posts]
				</div>

and underneath add:

<!-- / XBLGT Start -->
<if condition="$post[fieldXX]"><a href="http://profile.mygamercard.net/$post[fieldXX]">
<img src="http://card.mygamercard.net/mini/$post[fieldXX].png" width="150" height="100" border="0"></a></if>
<!-- / XBLGT End -->

It will look like below.

If you want it under your avatar add the code under here after the </if>:

<if condition="$show['avatar']">
				<div class="smallfont">
					&nbsp;<br /><a href="member.php?$session[sessionurl]u=$post[userid]"><img src="$post[avatarurl]" $post[avwidth] $post[avheight] alt="<phrase 1="$post[username]">$vbphrase[xs_avatar]</phrase>" border="0" /></a>
				</div>
			</if>
