easy, I've done this with my board since my users rarely know the dropdown html.
well it's just:
add this any where you want
HTML Code:
<!-- FOR PM IMAGE -->
<if condition="$show['pmlink']">
<a href="private.php?$session[sessionurl]do=newpm&userid=$post[userid]"><img src="PM IMAGE LINK" alt="<phrase 1="$post[username]">$vbphrase[send_private_message_to_x]</phrase>"></a>
</if>
<!-- FOR EMAIL IMAGE -->
<if condition="$show['emaillink']">
<a href="sendmessage.php?$session[sessionurl]do=mailmember&u=$post[userid]"><img src="EMAIL IMAGE LINK" alt="<phrase 1="$post[username]">$vbphrase[send_email_to_x]</phrase>"></a>
</if>
