If you have added the private reply plugin while using a previous version of gforum, your forum is still using the modified include_post_display.html for displaying posts. In 1.1.6, the template now controls the size of your user icons. This feature is not in affect if you are using the old modified template. Here is what you should do to fix this:

1) Go to the Admin pannel ->Templates->user templates-> include_post_display*

2) Click on RESTORE to return to the 1.1.6 template for this.

3) There is an error in the instructions for this plugin, a % was left off the end ADD this code:

JUST UNDER:

<%GForum::GUI::draw(
draw => post_display_options,
separator => " | ",
edit => "Edit",
delete => "Delete",
cant_post => "Can't Post",
quote => "Quote",
reply => "Reply",
a_attribs => ""
)%>

---

<%if user_accept_privmsg%>|
<a href="gforum.cgi?do=message_post_reply_write;post=<%post_id%>;<%hidden_query%>">
Private Reply</a>
<%endif%>

---

the % and location where to put this are missing in the instructions. The entire section should now read:

---

<%GForum::GUI::draw(
draw => post_display_options,
separator => " | ",
edit => "Edit",
delete => "Delete",
cant_post => "Can't Post",
quote => "Quote",
reply => "Reply",
a_attribs => ""
)%>
<%if user_accept_privmsg%>|
<a href="gforum.cgi?do=message_post_reply_write;post=<%post_id%>;<%hidden_query%>">
Private Reply</a>
<%endif%>

</b><%/body_font%>
</td>
