Displaying Images in Profile Block instead of Text?

[gorentals]

Thank you guys for helping me out. Here is my code in the Memberinfo Template at the bottom: I am also on Vbulletin 3.8.3

<div id="sidebar_container">
<!-- sidebar -->
$template_hook[profile_right_first]
$blocks[stats_mini]
<!--new block-->
<!-- $id -->
<div id="$id" class="tborder content_block">
<h4 class="thead block_title">
<a href="#top" class="collapse_gadget" onclick="return toggle_collapse('$id')"><img id="collapseimg_$id" src="$stylevar[imgdir_button]/collapse_generic{$vbcollapse['collapseimg_'.$id]}.gif" alt="" border="0" /></a>
<a name="$id"></a>
<span class="block_name">Codes</span>
</h4>
<div class="block_content" id="collapseobj_$id" style="{$vbcollapse['collapseobj_'.$id]}"><div class="alt1 smallfont block_row block_footer">
<if condition="$post[field15]">
<img src="$stylevar[imgdir_misc]/$post[field15].png" alt="$post[field15]" />
</if>
</div></div>
</div>
<!-- / $id -->
<!--new block-->


$template_hook[profile_right_mini]
$blocks[friends_mini]
$blocks[youtube]
$blocks[albums]
$template_hook[profile_right_album]
$blocks[groups]
$blocks[visitors]
$template_hook[profile_right_last]
<!-- / sidebar -->
</div>

<!-- end usercss -->
</div>

$footer

</body>
</html>

Ok I can see the Codes Block, but nothing shows. I have a Field called mk and its field15. What is entered in that field is just numbers. Is my code wrong? thanks for any assistance.
