if anyone is still having this issue - this has worked for me...

go to your current style and expand

registration templates/register and then 'customise'

find the phrase '$human_verfication' or

and just above it copy and paste the code in the quote below.

<fieldset class="fieldset">
<legend>$vbphrase[image_verification]</legend>
<table cellpadding="0" cellspacing="$stylevar[formspacer]" border="0" width="100%">
<tr>
<td width="100%" valign="top">
$vbphrase[please_enter_the_text]<br /><br />
<img id="progress_imagereg" style="display: none; float:$stylevar[right]" src="$stylevar[imgdir_misc]/progress.gif" alt="" />
<input type="text" class="bginput" name="${var_prefix}[input]" size="10" maxlength="6" />
<input id="hash" type="hidden" name="${var_prefix}[hash]" value="$humanverify[hash]" />
</td>
<td valign="bottom" align="center">
<img id="imagereg" src="image.php?$session[sessionurl]type=hv&amp;hash=$humanverify[hash]" alt="$vbphrase[registration_image]" width="201" height="61" border="0" />
<span id="refresh_imagereg" style="display:none"><a href="#">$vbphrase[refresh_image]</a></span>
</td>
</tr>
</table>
</fieldset>
<script type="text/javascript" src="clientscript/vbulletin_ajax_imagereg.js?v=$vboptions[simpleversion]"></script>
<script type="text/javascript">
<!--
vB_AJAX_ImageReg_Init();
//-->
</script>

you'll find the field just below the email verification.
I'm having issues getting the actual verification to work, but at least it can be seen now!

(will come back if i find out what's wrong'
